West Brom 1-1 Brighton
Hal Robson-Kanu is in a lot of pain and after treatment he limps off, grimacing as he does so. For the rest of this game West Brom are down to 10.
West Brom 1-1 Brighton
Bad news for West Brom as Hal Robson-Kanu appears to have a problem at the top of his right quad muscle. He's struggling to move, but the Baggies have made their four changes. He either stays on, or they play with 10.
West Brom 1-1 Brighton
The ball is played into the feet of Hal Robson-Kanu on the edge of the penalty area but he goes the wrong way, turning back into trouble instead of continuing the move and playing it to his right.
West Brom 1-1 Brighton
Ollie Parry:@WBA, external are sadly going to have to forfeit most of extra time, as half their team has to be up in time for school tomorrow.
West Brom 1-1 Brighton
We're under way with extra time, and we're now on BBC Two as well.

West Brom were more tactically solid in the second half but defensive errors have caused them to concede. It will be interesting to see if they become more expansive in extra time or aim to be more solid.
West Brom 1-1 Brighton
He scored Brighton's equaliser but should Florin Andone have been on the pitch?
Watch his late leveller and his earlier elbow to West Brom's Sam Field which could have seen the midfielder sent off in the first half.

When was the last time you saw a goal with someone holding on to the post when they score?
Well, here you go.
West Brom 1-1 Brighton
A few more clips for you. It looked like it could be a penalty for Brighton, but nope. Chris Hughton can't believe it.
West Brom 1-1 Brighton
Get yourselves comfortable. We've got another 30 minutes and maybe even a penalty shootout. The drama is not done yet.
West Brom 1-1 Brighton
Have Brighton won it? Nope. Substitute Jurgen Locadia glances a header into the net but has gone too soon and is offside.
West Brom 1-1 Brighton
Three minutes left for a winner or it's extra time.

A hush has descended around The Hawthorns. Both sets of supporters are more than aware that extra-time is looming! If if goes the distance, heaven knows what time the Brighton fans will get home in the early hours of tomorrow morning!
West Brom 1-1 Brighton
Brave goalkeeping from Jonathan Bond to deal with a dangerous ball into the box. But Bond takes no prisoners to punch clear.
West Brom 1-1 Brighton
Daniel Stevanato: Andone shouldn't even have been on the pitch to score. Saying that, it was absolutely garbage defending by West Brom.
Martin Warren: Looks like extra time then... don’t know what WBA have done there, poor defending.

It's terrible defending from West Brom.
Kyle Bartley and Craig Dawson both have to do better there and react but they don't and Florin Andone slips past them. His shot then goes straight through Jonathan Bond.
Florin Andone (Brighton)
He shouldn't be on the pitch after a first half elbow, but now Florin Andone has made it 1-1. It is a mess at the back with Craig Dawson and Kyle Bartley both thinking the other man is going to clean up the danger.
Instead, Andone nips in, slots a shot past Jonathan Bond and it is one-one.
Kyle Bartley
A very, very bizarre goal, but West Brom lead. Wes Hoolahan's free-kick is headed up, but not out, by Brighton's Dan Burn.
At the back post Kyle Bartley is wrestling with Leon Balogun. The Brighton man must feel he is about to get a free-kick and walks away from Bartley with the ball coming their way.
Unmarked, Bartley hooks the ball into the net from on the deadball line.
West Brom 0-0 Brighton
Kevin Kilbane
Former Republic of Ireland winger on BBC One
Brighton have looked more threatening than West Brom throughout the second half. The change of system has not helped West Brom and their visitors appear the stronger.
I think Chris Hughton will be happy with how his team are playing at the moment.
