Zoltan Gera is to undergo a scan to determine the extent of the knee injury suffered during West Bromwich Albion's FA Cup tie at QPR on Saturday. Jonas Olsson, Goran Popov, Steven Reid and Claudio Yacob are already sidelined while Youssouf Mulumbu has now joined up with DR Congo for the African Nations Cup.
Albion assistant boss Kevin Keen said: "Marc has got a little nick on his hamstring and, with Zoltan, we will have a scan over the next couple of days.
"Hopefully, fingers crossed, it's not too bad but we will just have to see. He (Gera) had a little twist and felt something so we will have to wait and see."
