Michael Carrick is hoping that he will not be forced into action as an emergency defender following a spate of injuries at Old Trafford.
Jonny Evans is also an injury doubt for the weekend clash with Bolton Wanderers, meaning that Carrick, usually a midfielder, could be pushed into the backline. He operated as a makeshift defender last season against Fulham at Craven Cottage - a match that United lost 3-0.
"[Playing in defence] did get a mention in the changing room," Carrick told MUTV. "I said to [assistant] Mike Phelan 'I don't fancy that again'.
"It is never nice to get the injuries of course. It is disappointing when you pick up a number in a similar position. But I don't think we are that desperate yet and hopefully I won't be called upon."
Meanwhile, United will be without goalkeeper Anders Lindegaard for around five weeks after he had surgery on a knee injury. Ben Amos has been recalled from his loan spell at Oldham Athletic as cover.
