FT: England 3 Scotland 2. Lambert comes off the bench to score with his first touch and give Hodgson's men victory.
And Lambert is then presented with another chance on the left side of the area, but his tame shot doesn't seriously trouble McGregor.
Lambert hits the post from close range! Doubt that'll spoil his debut but he really should have scored.
Steven Whittaker attempts an ambitious effort after Naismith played him into the left side of the area. His shot flies over.
Zaha has been causing problems down the right since coming on and after latching onto Oxlade-Chamberlain's pass, he drags a shot across the face of goal.
McGregor has to readjust his feet as a powerful Lampard shot comes towards him from 30 yards but he palms the ball out successfully.
Scotland get some brief respite from the rising England corner count, but Hutton can't do much with his right-wing cross.
What an impact! With his first touch, Lambert thumps home a header from Baines' corner. Pure unbridled joy in the celebration.
Midway through the second half, and we get two Scotland subs: Mulgrew and Conway ON, Snodgrass and Forrest OFF.
Almost a second goal for Welbeck - and it would have been a spectacular one. The Manchester United forward hangs in mid-air and executes an acrobatic volley but he can't hook his shot the right side of the post.
New captain Lampard is cautioned for a late tackle on Maloney near the halfway line. Three England players on yellows now.
A second change for England: Alex Oxlade-Chamberlain ON, Steven Gerrard OFF. Lampard takes the captain's armband.
A pretty remarkable stat from @OptaJoe on Twitter: '6 - Danny Welbeck has scored with all six of his shots on target for England. Deadly.'
McGregor gets down to his right to keep out Lampard's shot from just inside the area, and Baines can't get enough on the loose ball to seriously test the keeper again.
Walcott and Snodgrass are both booked after a flashpoint on the left. Hanley was getting pretty physical there too but escapes a caution.
That had been coming. England's Kyle Walker collects the first yellow card of the night for bringing down Forrest in midfield.
Welbeck rises to head down Gerrard's free-kick into the bottom corner and McGregor can't keep the ball out.
Good stop from McGregor down at his post to keep out Gerrard's looping ball in. The ball took a flick off Martin.
Hutton's cross from the right is chested down by Miller, standing in front of Cahill on the edge of the area. Miller's sidestep confuses Cahill and the powerful shot flies past Hart.
Walker strides down the right wing and whips the ball into the area. It gets stuck under Hanley's feet but Scotland manage to clear in the end.
Feedback from Man City season ticket holder @MazinNasralla on Twitter: 'You're wrong to blame Hart for Scotland's goal. The goal came through a ruck of England players, and he had no chance to react.' He may have a point there. Be interesting to hear Hart's view on it later.
Here's Wes Salmon on email from Canada: 'As a Man Utd fan, I'm pro our players featuring for England. But I honestly don't know why Welbeck keeps getting starting opportunities.' I think some of Welbeck's link-up play with Rooney has been decent, but he's not exactly looking dangerous out there.
Here's some half-time odds from Sky Bet: England to win 3-2 is 20/1, Scotland 2-1 is 14/1, Walcott to score next is 10/1 while Snodgrass is now 33/1.
Half-time: England 1 (Walcott 29) Scotland 1 (Morrison 11). So a good recovery from Hodgson's men after Hart's error allowed the visitors to take the lead. Your thoughts?
Rooney has the ball in the back of the net but he's been flagged offside from Gerrard's ball over the top. It's a bad flag from the assistant referee - Rooney was well onside when the ball was played.
'Magical Walcott, just when it was looking like same old, same old England, my faith is returning!' Paul in Dartford on email there.
Brown robs Wilshere just outside the centre circle and Miller feeds Snodgrass down the left channel. His cross-come-shot has to be put out of play by Jagielka.
Patient build-up from England, but Walker's right-wing cross is overhit and then Baines fails to do much with his left-wing delivery.
Wilshere's drive forward is blocked but Rooney seizes ball and a clever one-two with Welbeck leads to a shot from 20 yards, but it goes just wide.
An excellent defence-splitting pass from Cleverley down the right channel and Walcott is onto it like a flash. It looks like the Arsenal forward may have waited too long, but he cuts inside of Whittaker and finishes low from five yards before Brown can reach him.
Cleverley should have equalised there. Rooney lays off Walcott's cross in from the right but Russell Martin makes a heroic block. Even then, the England midfielder might have recovered to score.
Hutton is furious with the assistant referee for not giving Scotland a corner and it's justified - replays show the ball came off Welbeck last.
Scotland think they should have had a free-kick when Gerrard makes a heavy tackle on Snodgrass. Walcott counters but loses the ball and then Morrison blazes over from long range.
Walker bundles over Snodgrass and the German referee awards the Scots another free-kick. They look very comfortable at the moment.
England are looking to Gerrard to try and unlock the Scotland defence but his passes forward aren't threatening enough.
Gerrard looks to swing in a cross to the left for Baines but Scotland are resolute. The visitors have dropped deep to defend their lead.
Replays of the goal show Hart's reactions weren't up to scratch on that Morrison shot at all. Unsighted perhaps, but a goalkeeper of his quality should be saving them.
Welbeck headed the corner away but Walcott could only move it on as far as Morrison 20 yards out. His shot on goal was fumbled by Hart and the ball went in to give the visitors the lead. 0-1.
Walker gives away another free-kick for a foul on Maloney. Scotland play the ball right and end up forcing a corner.
First real chance falls to Rooney! After Wilshere won the ball, he fed it left to Baines and the left-back crossed for Rooney. Shot went across the face of goal.
Felix Brych from Germany is tonight's referee. He's given Scotland a free-kick just inside the England half.
Is there a more passionate national anthem than 'Flower of Scotland'? The sound of bagpipes and 20,000 Tartan Army voices fill this great stadium.
The players are coming out onto the pitch at Wembley, the FIFA anthem heralding their arrival. Atmosphere building.
Just been looking at Kenny Miller's MLS stats. In his last 11 starts dating back to June 1, he's bagged five goals and the Whitecaps have won seven of those games.
Roy Hodgson: 'There's been a fantastic response to the fixture from our Scottish friends.' Gordon Strachan: 'This is not your average friendly. We play to win.'
Scotland have just confirmed their bench for tonight. Essentially it's the rest of what was quite a large squad: Gilks (GK), Marshall (GK), McArthur, Naismith, Burke, Adam, Webster, Rhodes, Mulgrew, Bannan, Griffiths, Mackay-Steven, Dorrans, Conway, Boyd, Greer, Hammell.
Support for Scotland frontman Kenny Miller from 'Vancouver Whitecaps Sales Account Executive' @darrenmacki on Twitter! 'His form for the Whitecaps is pretty good in comparison to those who are still in preseason. #midseasonform #MLS'
Jack Wilshere will be winning just his eighth England cap tonight - although he is still 21 years of age, so has plenty of time to win some more. This is only the second time he's started alongside skipper Steven Gerrard.
James McLachlan on email has to get a mention because he's the first person who's contacted me to predict Scotland getting a result: 'I reckon it will be 2-1 to Scotland or a score draw!' Hedging his bets there.
Tom Cleverley has started every England game he has been available for under Hodgson. He very much looks like teacher's pet in this Three Lions team.
As mentioned earlier, Michael Carrick had to pull out of tonight's game and he's just tweeted via his @carras16 account: 'Frustrated with this eye infection. Should have been at Wembley... gotta watch it on the box. All the best boys.'
I asked for your predictions, you responded as follows. On email, 'proud Englishman' Christopher Green is going for a 3-1 home win, while on Twitter, @smargo_CPFC agrees - but adds that he's a '#terribletipster'. Hmm.
You may have seen pictures of the Tartan Army gearing up for tonight's game with some larking about in Trafalgar Square earlier. Police say they made only one arrest, with a Scotland fan taken away 'for being drunk and disorderly after he was spotted dancing naked in the fountain'. The message is - don't lift your kilts please.
How to beat Scotland, from Keith Landles in Edinburgh on email: 'If Roy has any brains, he will simply tell Walcott to play outside left and rip Hutton's heart out. How this guy continues to get a game for Scotland has to be one of football's great mysteries.'
Here's a tasty little suggestion from Sky Bet's Dale Tempest on Twitter at @SkyBet_Dale: 'Must be 2/1 Snodgrass to be booked and 9/1 1st card. Last year, 8 cards. He could get a yellow if he was the only person on the pitch!!'
Staying on the subject of Lambert, here's Southampton season ticket holder Liam Whitlock on email: 'Surprised that a Saints player even got called up, never mind included in the squad for tonight! Think Lambert will get the second half, he will come on for a not fully-fit Rooney.' Liam fancies a 4-1 England win. What's your prediction?
Here's some of our views on Twitter on England's starting line-up. @Ross_Hemsworth says: 'The same old names bar one or two in tonight's England squad! How about some imagination Roy?'
Meanwhile, Rio Ferdinand has tweeted to say: 'At the Cinema watching The Smurfs.' However, the former England defender was quick to post a follow-up message insisting he would be back home in time for kick-off at Wembley.
The Manchester United connection could reap rewards for England tonight. Fancy Rooney and Welbeck to both get on the scoresheet against Scotland? That's been priced up at 15/2 by Sky Bet.
Southampton fans will have to wait to get a sight of their hero Rickie Lambert in an England shirt. What do you make of Roy Hodgson's selection tonight? Let me know. Email email@example.com or tweet me at @jonboy79.
So five changes for England following their encouraging 2-2 draw in Brazil last time out. Kyle Walker is preferred at right-back, while captain Steven Gerrard forms a midfield trio with Jack Wilshere and Tom Cleverley. In attack, Danny Welbeck gets the nod. Dropping to the bench are Glen Johnson, Phil Jones, Frank Lampard and James Milner. Michael Carrick pulled out through injury earlier in the day due to an eye infection.
England substitutes: Foster, Ruddy, Johnson, A Cole, Jones, Smalling, Milner, Lampard, Defoe, Lambert, Chamberlain, Zaha.
Confirmed England team: Hart; Walker, Cahill, Jagielka, Baines; Gerrard (c), Cleverley, Wilshere; Walcott, Rooney, Welbeck.
We should get the confirmed England team through shortly. Daniel Potts on email is hoping to see a certain Southampton striker get a proper run-out and time to impress: 'Hoping England give Rickie Lambert at least 45 minutes. He has earned it.'
Kenny Miller wins his 69th cap tonight at the age of 33. Strachan has plumped for the Vancouver Whitecaps striker to lead the line but @bakeyreilly is none too impressed. He's tweeted: 'Got to assume that Kenny Miller is picked as a gesture of loyalty for past services rather than current potential form.'
Snodgrass' 26th-minute goal gave Scotland that shock win over Croatia in Zagreb just over two months ago. If you fancy him to notch again for his country in a 1-1 draw tonight, you can get odds of 125/1 with Sky Bet. It's one of their Scorecast Boosts.
Scotland will be looking to close the gap on England tonight. In their 110 previous international meetings dating all the way back to 1872, the Three Lions have come out on top in 45 encounters - four more than the Scots.
Strachan has kept faith with the same defence that earned Scotland a 1-0 win away to Croatia in World Cup qualifying Group A in June. Robert Snodgrass, Shaun Maloney and James Morrison are also retained. The three changes are the returns of captain Scott Brown, James Forrest and Kenny Miller. Barry Bannan, Leigh Griffiths and James McArthur make way and should be among the substitutes.
What are your thoughts on Scotland boss Gordon Strachan's team selection tonight? Let me know by emailing me at firstname.lastname@example.org or tweet me at @jonboy79.
Confirmed Scotland team to face England: McGregor, Hutton, Hanley, Martin, Whittaker, Snodgrass, Brown (c), Morrison, Forrest, Maloney, Miller.
