After victory at Everton yesterday, Ferguson said: "He will be fit for Wednesday, we have taken medical advice and he only started training on Monday.
"And after only five days he is a bit short of fitness, he trained today and will train again tomorrow and through until Wednesday."
And on the last-ditch win, Fergie said: "It was a great result, there was some quality showing through. We all know we have not got our strongest side out at the moment due to injuries, but there is a good togetherness in the squad and it was a strong team effort.
"When we get our forward players back from injury we will be all right."
