Manchester United manger David Moyes has confirmed he needs to check on the risk of selecting Wayne Rooney before he sets a comeback date for the striker.
Rooney was forced to miss the Barclays Premier League trip to Liverpool at the end of last month and England's World Cup qualifiers against Moldova and Ukraine after suffering a nasty head gash in an accidental training ground collision with Phil Jones.
The 27-year-old posted pictures of the cut on-line to prove his absence was fully justified.
And now Moyes must decide when to bring Rooney back.
"He is in great physical shape," said Moyes.
"Obviously he has a cut right in the middle of his forehead which could split because the skin is very thin.
"But he has had his stitches out and it has knitted.
"We just have to see where the level of risk is with his injury."
Moyes also has doubts over Rafael and Phil Jones, who have hamstring and ankle problems respectively ahead of the clash with Crystal Palace.
However, he does have Marouane Fellaini available following his B£27.5million arrival from Everton.
United are just a point better off than newly-promoted Palace heading into the match, but Eagles boss Ian Holloway does not read too much into that.
"I think it is an honour going to Man United, whatever time it is, whoever the manager is, whoever is in charge," he said.
"At this moment in time they are in a transitional period.
"They've got a new manager, who was chosen by the last one - you don't get much better on your resume than that. To hear 'I want him to replace me' must be an honour.
"But the fact of the matter is David has to make his mark on Manchester United - I've got to make my mark on Crystal Palace.
"Is it a good time to play them? I will tell you after the game."
