Another attacking change for Peterborough. They don't want penalties. Tiny playmaker Erhun Oztumer - who some Posh fans have apparently dubbed the Turkish Messi (?!), replaces Paul Taylor.

A quick swig of water, some final words from the coaching staff. Fifteen minutes for someone to nick a winner.

Albion looking likeliest to nab the second, Salomon Rondon finally showing glimpses of why he was bought for £12m. He chests down a high ball to create some space, but blasts over from distance.

"We are going to have to rename Michael Bostwick Mr Block the amount of times he has stopped West Brom tonight."

Peterborough defender Michael Bostwick is one of these players who just knows how to snuff out danger. He flings himself in front of James McClean's goalbound shot, then Jonas Olsson head over moments later.

Another change for Peterborough. On comes Marcus Maddison, a left-footed attacking midfielder, who apparently attracted the attention of Leeds United in January.

Martin Samuelsen has ran rings around the Albion defence at times. The teenage Norwegian twists, turns, shimmies and finally flicks his way into a shooting position, just leaning back as he fires over the Albion bar. Decent prospect.

Albion still threatening as the teams take turns to attack like a pair of NBA sides. The latest away venture ends in Craig Gardner having a shot blocked. Albion being restricted to long-range efforts.

Peterborough still playing at a high tempo going forward, but look weary at the back when Albion go forward. Darren Fletcher has a shot blocked on the edge of the home penalty area.

Jordan Booth: This is such a typical Tony Pulis team, pile the defence and hope for a counter, really boring.

Jon Taylor has looked sharp for Peterborough tonight. The winger cuts in from the right, is allowed to drift across the edge of the Albion box before laying off to Souleymane Coulibaly. But the sub loses his head and lashes one wide from 18 yards.

"It's important for Peterborough to move this ball quickly. They are expending a lot of energy running with it and we are into extra-time here."

An early slip from Darren Fletcher almost lets Peterborough in, but Albion regroup to snuff out any danger.

Right then. Ready to rumble? The two teams are. On we go...

Posh boss Graham Westley gees up the London Road crowd, using his hands to encourage the home fans to make some more noise. Then he goes for a gentler approach with forward Souleymane Coulibaly, putting his arms around his shoulders as he relies some importantn instructions.

"Now you pick up the ball Souly and stick it in that *points* net. Got it? Good."

"Peterborough have been the best team over 90 minutes and their manager can be proud. They have given everything. There hasn't been anything between the two sides on the pitch."

Nope, our hero of the night will not be revealed for another 30 minutes or so. Extra-time will be needed to separate the two sides. And, gulp, possibly penalties...

Tell your partner that you're keeping hold of the remote control for the next 30 or so minutes...

A bit of head tennis in midfield. Frantic stuff. Who's going to be the hero? Anyone??

We showed you the replay of Peterborough's goal. Well, here is the Baggies' equaliser...
