West Brom midfielder Paul Scharner is to undergo a scan on his injured wrist before it is decided whether he will be available to face struggling Aston Villa on Saturday at The Hawthorns.
The Austrian did not train on Tuesday or Wednesday as a result of the problem, which he sustained after coming on as a late substitute in last weekend's shock win at Liverpool.
And Scharner, who last October scored the winner in West Brom's 2-1 derby victory at Villa Park, will now undergo further medical assessment.
West Brom will hope to have the midfielder available to their face Midlands rivals and they are also optimistic Marc-Antoine Fortune will be fit after missing the trip to Liverpool with a hamstring injury.
Bumps and bruises
"He's not trained today and he'll have a scan to see if there is a great deal of damage or not," assistant head coach Keith Downing told West Brom's official website of Scharner on Wednesday.
"He fell on it during Sunday's game.
"We have the usual bumps and bruises but in the main everyone trained yesterday and is upbeat.
"Marco could be considered by the end of the week, fingers crossed, depending on the next day or two of his rehab.
"It would be an advantage to have him back."
