The Scot has been sidelined since the start of February with an ankle injury but has recovered in time to be in contention for Palace’s FA Cup semi-final against Watford at the weekend and is set to be given a run out against Louis van Gaal’s team.
With Sunday’s trip to Wembley in mind, manager Alan Pardew is set to ring the changes for the visit to Old Trafford after revealing that Joel Ward, Scott Dann and Joe Ledley will all be rested.
“McArthur’s back for the Man United game, which is really good news,” said Pardew.
“Yala’s [Yannick Bolasie] struggling a little, [Joel] Ward will miss tomorrow’s game.
“Scott Dann and Joe Ledley have knocks. They’ll make Sunday, not Man United.”
Pardew also confirmed he is not willing to discuss any new contract with chairman Steve Parish before the club’s Premier League status is secured.
“Until we’re mathematically safe we won’t do anything on contracts,” he said.
