United manager Simon Grayson is refusing to rule out a weekend return for Scotland international Robert Snodgrass.

Robert underwent an appendix operation between Christmas and the New Year and missed the games against Barnsley, Burnley, and Arsenal.

But the winger is back on the training ground and could yet figure in Saturday's clash with Crystal Palace.

"Snoddy worked with physios on Monday and Tuesday and was out training on Thursday," said the boss.

"As it stands, I'm not ruling him in or out. It's only been two weeks since the operation, but he's coming on nicely and has done well. We'll see how he is on Friday.

"He still won't be 100 per cent, but it's positive news for everyone and it may be that he travels, does some work down there, and we'll see how he is."

The boss reported no new injury worries following the Arsenal game, but Leigh Bromby (calf) is ruled out.

The boss also added that both Jonny Howson and Davide Somma are making good progress from their respective injuries.
