Boult - who did not bowl in England's second innings due to a side strain - survives the rest of the over - Swann's the first spinner to take 10 wickets in a Headingley Test since Derek Underwood achieved the feat against Australia in 1972.
For the second time in the match Bracewell is caught at silly point by Ian Bell. Excellent grab, too, as it went at a pace as the batsman pushed forward. That's Swann's sixth wicket in this innings, giving him a 10-wicket haul for the match.
Well played Wagner. He ducks the short stuff that comes his way (including one that is so high it's called a wide) and is solid in defence to anything pitched in his half. 55 overs left today, says Bumble. One way or another, I don't think we're going to get them all in.
There was definitely a noise as the ball went in between bat and pad, but Hot Spot showed it was the latter. Bracewell did not find life easy against Swann. Cook posts a slip, gully and two close catchers. Shame this urgency wasn't shown earlier in the match, then we could all be watching Dickinson's Real Deal by now...
Bracewell's insistence within a second that he wasn't out was the indication there was no inside edge involved. He survives and England still need two more wickets.
Or is it? Swann gets a delivery to turn sharply out of the footholes and after hitting Prior on the arm, Root takes the easy catch moving backwards. Umpire Davis' finger goes up, but Bracewell immediately calls for a review.
Wagner survives the three remaining deliveries, the last of which is a decent short ball that forces the leftie to take evasive action. And what's this I spy? Umbrellas going up...this could be a very, very little window.
Bumble has checked the forecast and says we're right on the edge of some foul weather - that man is from Lancashire, so he knows all about foul weather. Time is vital. Here's Finn to finish the 66th over.
England are out there ready and waiting as New Zealanders Doug Bracewell and Neil Wagner emerge from the safety of the Headingley dressing room to a dreary Tuesday afternoon in Leeds.
2.40pm: Good news...for England. Play is due to resume at 3pm.
2.10pm: The highlights of the dramatic draw in Auckland have been aired, oh to see such sunshine in Blighty. Back at Headingley, it's wet, wet, wet.
1.55pm: More light drizzle, than heavy rain. You know, the fine stuff that soaks you through. The wait goes on for England, and the spectators inside the ground. Few more have come in since it's been announced it's free for all to get in now - considering the game is in Yorkshire, I have expected a full house by 1pm.
1.25pm: The groundstaff have been out on the field, dragged a rope around to try and take away the moisture, then disappeared back inside. "It's set in," says David Gower. "It's very grey at Headingley". Perhaps that's because Leeds Rhinos have lost three games in a row, David? Perhaps it's just because England should take legal action against the word 'summer' being used any more.
Hmm, the entire square is covered and a quote from the ground says it's raining "quite hard". Much for England to ponder, as well as which cake to choose from the selection.
Hope springs eternal for Ian Smith in the Sky Sports commentary box. "It's really starting to get to me that it's raining again," he says rather sarcastically. His over-riding emotion right now? "Hunger!"
Umpire Erasmus is either wanting someone to fetch him a sandwich or he's signalling that an early lunch will be taken. 40-minute break now, during which time England will hope the dark clouds clear and play can get back underway. That's fine, provided it doesn't stop inside five minutes and all the players are too busy tucking in.
Bracewell gets a single off the first ball towards mid-wicket, then Finn delivers a brute of a ball to Wagner that he does well to get over the top of and deflect down towards gully. Oh oh, the umpires are getting together...yep, it's raining heavily enough for the players to be taken from the field.
Wagner survives the final two balls of the Swann over with plenty of close fielders for company. So Swann becomes the first England spinner to take a five-for at this venue since John Emburey achieved the feat against Australia back in 1985.
No repreive for Southee this time when he edges Swann, Trott taking a sharp chance to his left that is much closer to him than the one he dropped earlier. And so ends an entertaining know from Southee of 38 from 41 deliveries.
50 stand up for the eighth wicket (and it's only taken 35 balls) thanks to 10 runs from Bracewell off Finn's bowling. Four of them come with a glorious cover drive on the up, while the other six are via a rather scratchy hook that he gets more than enough of. Swann to continue, the rain looks to be fast approaching Headingley.
Southee's coming out with all the shots now, taking a pace down the pitch and then driving a delivery tossed up way outside off for four through the point region. However, he gets a life from the fifth ball when a thin edge can't be taken by Trott at slip one-handed to his left. Southee finishes the over with a slogged six over deep mid-wicket and England perhaps are contemplating pace from both ends, if the light allows. Swann, meanwhile, looks an unhappy bunny.
Finn's first ball of the day is slotted by Southee over the head of the fielder at deep square leg, albeit only just. He's a happy hooker, apparently. The mind boggles. The next ball is swung out to Root in the same position, but never comes close to carrying. Dark clouds are definitely closing in, plus there are a few spots of rain suddenly.
Bracewell shows he knows which end of the bat to hold, playing a lovely cover drive to a full delivery. 'Rubbish', says Swann. He might have said something even worse after the following ball, as it's a long hop that deadly Doug slaps away for three more. Southee keeps the strike with a single down the ground off the last ball, and now it's Finn to come into the attack for Broad. And the dark clouds are gathering...
Bracewell gets off the mark, then Southee finishes the Broad over with a flourish, hitting the seamer straight back over his head for four. Broad heads straight off the field after his over is complete, surely for some treatment on the knee injury he picked up taking the catch from McCullum. Meanwhile, news from Barnsley - it's raining.
With McCullum gone, the commentators wonder how defensive the remaining Kiwis will be. Considering Southee has a go at the first two deliveries of the latest Swann over, I think we have the answer. He makes contact with the second attempt, bunting it over short mid-wicket for a couple. There are also four byes as one turns sharply past both batsman and wicketkeeper Prior. Runs don't matter, wickets do.
Broad is holding his knee after taking that return catch, but the pain has led to some gain as England now have not one but two ends to bowl at. Will Cook now go all-out attack? Probably not.
Broad bowls McCullum! Shame the batsman had stepped away in the run-up to make it a dead ball. However, the next delivery sees the Black Caps skipper bunt a full toss back towards the bowler, with Broad taking an excellent return catch diving low to his left.
Southee takes a single off the fifth delivery, then McCullum gets a real turner off the last. He's worked his way right across the stumps but it's bounced too much, meaning England wisely don't opt to use/lose their last review. It also went for a leg bye, so New Zealand's skipper is on strike to face Broad, who has dismissed him all three times so far in the series.
McCullum gets off the mark with a flick to deep square leg from the second ball of the over. Southee looks a bit uncomfortable against the short ball, but conservative Cook doesn't have a short leg in place. Ball wouldn't have carried in truth from a deflection onto thigh, but it does seem a position England could do with introducing. A flick off the fifth ball means Southee will have the strike for the next over bowled by...Swann.
Southee blocks the two remaining deliveries in the Swann over that was stopped last night due to bad light. Interesting to see if England stick with the spinner or turn (no pun intended) to pace from both ends. For now it's going to be Stuart Broad from t'other end.
Rings out around what is, to be honest, an almost empty Headingley. England need four wickets - New Zealand 310 runs. Lunch is still set for 1pm, so the hosts won't want to be going in for their Pot Noodle knowing there's still work to do.
Good news (for England fans)! Play will start at 11.45am and England are now out warming up. All covers are off the ground.
Saker thinks England have a healthy battery of fast bowlers: "There's a big schedule ahead of us and we need as many fast bowlers as we can. Tim Bresnan, Chris Tremlett, Graham Onions...they're all on the outskirts of the team, we've got a good, strong fast-bowling base." He's also been impressed by Somerset's Jamie Overton.
Saker also has some good words for Steve Finn, who removed Dean Brownlie last evening with a superb short ball. "We need some sort of variation and he gives you that - he gives you pace and bounce that you sometimes need," the Australian says of the 'Watford Wall'. "He's young and still learning. He always wants to learn. He tries new things and sometimes it doesn't work. He's a fantastic guy to work with and he's always trying to get better."
England bowling coach David Saker has been impressed with his attack in this series, even if they may not get the chance to take four more wickets today. "It's been impressive that they've shared the load around," he tells Nasser. "We worked really hard before the series making sure we would be able to move the ball. We've done that quite well here and it's something we have to make sure we are on top of for when we go to another country."
If you want your say on this match, England's approach to it, Trott's batting, Cook's field placing, ignoring weather predictions, or anything else that I've not included in that list, send an email to rob.lancaster@bskyb.com, or alternatively tweet to @SkySportsLanny
David Lloyd is the voice of the people, apparently - "You look at Twitter, and England's supporters are not impressed with the way England have played this game. The displeasure is there in the way that they've gone about winning this Test."
Those covers on the run-ups are off, and so are the main ones! This is for an inspection at 11.20, but it also suggests the conditions are improving.
We're should be underway now - instead we're watching further covers being put back on around the bowlers' run-ups. There may be a 'window of opportunity' this afternoon, apparently. The actual window says it's wet, and the groundstaff are going to need time to do some work once the rain has stopped.
Ian Smith is the lone Kiwi in the Sky Sports commentary box and he is loving this situation - "New Zealand have been given a lifeline here - we're 150-6 and we can't believe our luck. We're being given respect we don't deserve after being outplayed in this Test match."
And welcome to over-by-over coverage of what should be the fifth day of the second Test at Headingley. Instead, though, it's weather watch in Leeds. The covers are on, there's an inspection at 11.20am
