Manchester United's star striker Wayne Rooney is in doubt for the club's midweek Champions League football clash with Valencia in Spain, after an ankle injury forced him from the field during their 2-2 Premier League draw with Bolton.
The England international has been carrying the injury for some time and looked lethargic before being replaced by Italian rookie Federico Macheda shortly after half-time.
A fully fit Rooney is vital to the Red's Champions League campaign but United's assistant manager Mike Phelan concedes the striker may miss the match against Valencia on Thursday morning.
Winger Ryan Giggs is a definite non-starter, with the Welsh wizard's hamstring injury proving troublesome.
