Speaking in his post-match press conference following Crystal Palace's loss to Manchester United, Eagles manager Roy Hodgson confirmed that the injury which forced Patrick van Aanholt from the pitch is a dislocated shoulder.
"It’s a bad injury and it’s going to keep him out for a long period," Hodgson said. "They’ll look at it tomorrow [by running a scan] and find out what the next step will be for him.
"I think he’ll require an operation and that’s bad news for us.
