A late Bournemouth equaliser denied them victory in their last Premier League match, but the Seagulls are still flying high and a win could move them into the top half of the table.
Here's the team that Chris Hughton might select at the Hawthorns:
Australian keeper Matt Ryan will return in goal after Tim Krul deputised against Crystal Palace.
The central defensive partnership between Lewis Dunk and Shane Duffy has been the highlight of Brighton's season so far, and they should both return after being rested in the FA Cup.
Austrian Markus Suttner seems to have nailed down the left-back slot ahead of Gaetan Bong. Club captain Bruno is expected to return at right-back in place of Ezequiel Schelotto.
Dale Stephens was one of the few regulars who kept his place against Palace and it was he who opened the scoring in that match. He's expected to start alongside Davy Pröpper, who replaced him after an hour on Monday.
Anthony Knockaert's goal against Bournemouth was his first since October, and he will pose his usual threat down the right wing. Solly March will return on the other side after his record of playing in every league game so far this season was ended on New Year's Day.
Pascal Groß scored two and assisted the other when these two sides met at the Amex Stadium back in September, and his form has been crucial to Brighton's success so far this season. The German will take up his usual position behind the main striker in a 4-4-1-1 setup.
Tomer Hemed and Glenn Murray have been fighting for the centre-forward role all season but Murray has seven goals to Hemed's two and is the logical choice to lead the line after his match-winning goal against Palace.
