Blackburn new boy Jermaine Jones is in contention for the game along with Roque Santa Cruz, who is poised for his first start since rejoining the club on loan from Manchester City last week.
Ryan Nelsen (knee) and back-up goalkeeper Mark Bunn (back) are slight doubts but David Dunn (leg) is fit.
Steven Nzonzi (hamstring) could also return while Keith Andrews and Vince Grella are close to fitness after lay-offs. Defender Phil Jones is now the only long-term absentee.
West Brom welcome back key defender Jonas Olsson from suspension.
The Swede returned from two and a half months out with an Achilles injury in the FA Cup defeat by Reading two weeks ago but was sent off after 15 minutes and served his one-match ban against Blackpool last weekend.
Olsson played in a behind-closed-doors friendly against Walsall yesterday and is set to be thrown straight back into the action by boss Roberto Di Matteo.
Pablo Ibanez also came through that match unscathed after recovering from a hamstring injury but Graham Dorrans is a doubt after twisting an ankle while Steven Reid (knee) is poised to return to training next week.
