Hello and welcome to the liveblog of West Bromwich Albion vs Crystal Palace in the FA Cup

That's all from me. Bye.

It's all over! Palace win 2-0 and are in the fourth round. West Brom are out and Keith Downing's unbeaten run lies in tatters.

GOAL! Bolasie runs and runs and runs and slides the ball to Chamakh for a tap-in! Palace are in the fourth ruond!

West Brom push forward again. Rolled into Berahino but it's cleared by O'Keefe and Bolasie breaks clear....

Amalfitano fouls Bolasie to stop a breakaway and gets a yellow - the referee should have played on, there. Big calls, big calls.

Gera with a huge chance! His volley from inside the area is deflected just wide!

This would be the first time Palace have made the fourth round since 09/10

Palace concede another corner which is played in by Amalfitano; it loops up into the air and falls to the feet of Berahino who - duh - shoots without success. Eight starts and seven goals for him: it's no coincidence.

Parr demonstrates Palace's plan for the final few minutes: he lets the ball bounce out rather than playing it. Fair enough, really: they've done what they have to.

Corner to Palace, played short, then dinked into the box, then Gayle is penalised. Anti-climatic for us, but not much to bother about for Palace - more minutes off the clock.

Offside goal from Dwight Gayle! Quick passes get Gayle in, he puts the ball past Foster, but the whistle's already gone.

Sessegnon tries to start another move, under pressure, but his ball out wide to Sinclair goes out off the top of his head.

Spin and shot from Berahino is blocked and out for a throw-in. His team has been low on ideas, but you have to respect how many shots he's managed regardless of that.

Sessegnon rolls the ball out wide to Sinclair, West Brom momentum behind him - players piling forward - and he hits it against Dikgacoi's legs. Pooooooor.

Yacob off for Sessegnon.

Corner in, Speroni flaps, Parr tries to win the header, Berahino gets the last touch....and it's over the bar.

West Brom move forward, Gabbidon intercepts a high ball, conceding a corner as he does so.

So Chamakh goes behind Gayle. Maybe hoping the ball sticks up front a bit better. Definitely hoping Chamakh can help out at the back too.

Puncheon and Chamakh on for Palace. Williams and Bannan off. An attacking substitution, of sorts.

Mariappa was booked for a foul on Sinclair a few minues ago.
