Carlos Tevez has sustained a badly bruised ankle after being carried off during United's narrow New Year's Day win over Birmingham.
The Argentine striker, scorer of the game's only goal, was substituted after 71 minutes, having suffered a heavy challenge late in the first half.
Despite fears that the injury could be serious, a club spokesperson told ManUtd.com: "Nothing is broken, Carlos Tevez has just got a badly bruised right ankle."
Sir Alex Ferguson has already confirmed Tevez is a major doubt for Saturday's FA Cup trip to Aston Villa, but the likely return of Wayne Rooney from a virus should provide timely compensation for the Argentine's absence.
