West Brom's Hungarian midfielder Zoltan Gera will be out of action for the "foreseeable future" after sustaining a serious knee injury playing against Tottenham on Saturday, the club revealed on Monday.
Baggies boss Roy Hodgson said that the Hungary captain will undergo further scans this week but added that he feared the worse.
"Zoltan has done really well since coming into the team three games ago and his performances quickly justified how highly we rate him," he told teh club's official website.
"We still don't know for sure how long he will be out for but we know we won't be able to call on his services for the foreseeable future. This will be a major blow both on the training pitch and the match arena.
"Zoltan is now in the hands of our excellent medical and sports science department and we just have to hope and pray that his stint on the sidelines is not an overly prolonged one."
Gera initially joined West Brom from Ferencvaros in 2004, making over 150 appearances before signing for Fulham four years later.
He moved back to the West Midlands over the summer, signing a two-year contract.
