Manchester United manager Sir Alex Ferguson rates Paul Scholes as "doubtful" for Monday's Barclays Premier League showdown with Arsenal at Old Trafford.
The veteran midfielder has not featured since the victory over Rangers last month, when he picked up a groin injury.
Scholes had been expected to play some part in United's 1-1 draw with Valencia at Old Trafford last night but, after a minor setback in training, Ferguson fears he will not be able to call upon his influential playmaker against Arsene Wenger's men.
"Paul tried training on Sunday and came off," Ferguson told MUTV. "He will be doubtful for next Monday."
The United camp are rather more optimistic about Rio Ferdinand, who was forced out of last night's game five minutes into the second half after feeling some discomfort in his hamstring.
"Rio felt it at half-time," said Ferguson. He wanted to try it but it still felt tight. We weren't prepared to take a chance. There was no point because we had Chris Smalling to come on. He has six days and I am sure he will be okay for Monday."
