West Bromwich Albion midfielder Zoltan Gera has suffered a serious knee injury, scans have revealed.
Gera was forced off in the 21st minute of Saturday s 3-1 Premier League defeat at home to Tottenham.
The 32-year-old will undergo further medical tests this week to determine the extent of the damage and allow the planning of his rehabilitation.
The Hungary captain returned over the close-season to the club for which he made over 150 appearances between 2004 and 2008, after signing from Fulham on a free transfer.
Baggies manager Roy Hodgson told West Brom s official website: Zoltan has done really well since coming into the team three games ago and his performances quickly justified how highly we rate him.
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.
