Keane should play against Newcastle reserves tonight, originally due to be played at Moss Lane in Alty, but now switched back to O.T.
Fergie:
"Roy may possibly play in the reserves on Thursday," If he does, that's a great start for him. We then know we can have him in the New Year programme."
"Roy has been out for almost four months but the game will certainly be of benefit and it gives me an option of putting him on the bench on Sunday," Ferguson said.
"That is certainly an option if he comes through healthy and enjoys himself. I don't really need to put demands on him.
