It's elation for Huddersfield but deflation for Sheffield United as they fall at the final hurdle in the most painful of ways. The Terriers will celebrate tonight though as Simon Grayson's side prepare for life in the Championship next season!
MISS - Simonsen fires it over the crossbar and Huddersfield are promoted into the npower Championship!
MISS - Williamson's penalty is also saved! Another predictable effort and Smithies saves excellently.
END OF EXTRA TIME. Huddersfield 0 Sheffield United 0. A place in the Championship will be decided on penalties!
Williamson crosses in from the right but Porter is marginally offside as penalties appear to be imminent.
The whistle blows and a foul is given against Montgomery after Williamson's delivery to the far post.
Williamson's effort is on target but straight into the arms of Smithies. A simple save and a huge waste at this stage of the game.
The game has exploded into life! Firstly Clarke has a header cleared off the line by Montgomery before up the other Porter is floored on the break by Johnson, who is booked for his efforts
Lee comes together with Doyle, the latter charging into the striker's run and Huddersfield have a free-kick 30 yards out.
The ball travels down the line to Lee who produces a fierce shot which is parried by Simonsen! Fortunately for United, no Huddersfield player is there to follow up and the Blades clear.
Quinn is down with cramp, which holds up play but Roberts earns Huddersfield a corner which is cleared bravely by Maguire.
Quinn is outstanding as he cuts inside Morrison and Hunt before firing at the near post which draws a smart save from Smithies!
Williamson intercepts with vigour from Doyle, but Woods intercepts a loose pass from Porter and the midfield congestion battle resumes.
A Roberts' free-kick is pacey but always too high for Morrison to reach at the far post. Goal kick to the Blades.
Williamson cuts inside Morrison but in controlling the ball he fouls Hunt and a spell of Blades pressure is brought to an end.
Marc Chadwick from New Zealand asks: 'What happens if it ends up 0-0 after penalties?' Good question, looking possible the way this is going!
Porter and Quinn both exchange chances to shoot until Porter eventually lets rip forcing an outstanding diving block from Clarke.
Quinn gets away from Hunt on the counter though and the full-back can do nothing but foul him or let him pass. He fouls in and it's a Blades free-kick.

Again, as soon I say that a chance occurs as Porter nods on Quinn's ball into the path of Morrison who concedes a corner.

Rhodes has a pop but it bobbles along the ground comfortably for Simonsen. I said extra time is imminent, I lied. We could be in for a frantic showdown at Wembley.
Woods hacks the ball into the fans to deny Flynn whipping a cross in, but Hill eventually gets one away and Porter beats both Terriers centre-backs to narrowly glance a header wide.
Huddersfield again come close as Ward drifts another pin point cross into the box, with Clarke getting on the end of it but he aims his header wide!
Great chance for Huddersfield! Rhodes' header brings a save from Simonsen before Lowton clears off the line!
Having said that, Rhodes nearly creates an oppotunity for himself as Maguire is drawn into an excellent clearance.
Lowton calmly plays back to Simonsen under pressure from Novak, with extra time looking a certainty right now.
Miller looks for Rhodes but can only find Smithies with a poor ball, before moments later, Higginbotham is dispossessed by Hill.

Free-kick to United, which Williamson fires in, with Maguire looking to connect before Clarke powers it out for a throw-in.

It's been a much more positive start from Huddersfield as Woods searches for Novak down the line, which Lowton reads and clears accordingly.
Doyle clashes with Johnson in the air and both take a tumble with head pains but both are now back up on their feet.
Woods crosses in from the left, the ball falling to Ward whose excellent effort cannons off the crossbar. The first real chance of the game and hopefully a sign of things to come.
Gary Cleaver writes: 'As an MK Dons supporter I have seen both sides recently, this one was always going to be close, and with the temperature at pitch level well into the thirties, the longer it goes on the slower it will get. It could go all the way to penalties, if it does the bucket in the corner of the dressing room will definitely be full. If it is to finish in normal time I'd go for 1-0 Sheffield United.'
Hunt demonstrates excellent pace to skip past Flynn, but his ball i't the best and ends up travelling out of play. Hunt looks the best form of service for Huddersfield today though.
Cresswell backs into Clarke illegally and the game comes to a halt once more with a Terries free-kick.
Doyle's ball is too long for Cresswell, with both sets of strikers really feeding off scraps for the time being.
Hill makes a solid challenge on Higginbotham, with the winger's progress down the right cut off in its tracks.
Rhodes makes a menacing run across goal, leaving players behind at will but his shot lacks the pace to trouble Simonsen and it trails wide.
Doyle can only clear as far as Ward, with Hill getting on the end of his delivery as Simonsen this time was left flapping at the cross.
Montgomery's driven effort comes off the feet of an unsuspecting Terriers defender, but the attack ends as Hunt is hacked down by Flynn, who is reprimanded by the referee.

After a really promising run from Woods, he lets his run down with a poor cross that practically lands behind goal. Goal kick for the Blades.
Cresswell falls under the challenge of Clarke but no penalty is given, and rightfully so as he looked to have been falling before the tackle anyway.
Morrison heads away the latest delivery from Williamson, with both teams looking sturdy defensively right now. You sense either a mistake or an act of genius could be the difference today.
