Crystal Palace manager Alan Pardew has revealed that winger Wilfried Zaha may be forced to sit out the FA Cup final against Manchester United later this month.

Pardew said at a press conference today that the 23-year-old was struggling with a hamstring strain and may not be fit in time for the Wembley showpiece against his former club.

"Wilf still has a problem that will still keep him out for this weekend," Pardew told reporters. "Hopefully he'll be okay for the final. Wilf's a naturally fit guy.

"He actually did the injury before the semi-final. We scanned him on the Monday afterwards and saw there's a slight tear there.

"We can't take a risk with him, it really is about risk his injury. There's no way he can play this weekend [against Stoke City], but he could possibly play at Southampton [on the final day of the Premier League season]."

Pardew also said that the club will fine midfielder Lee Chung-yong for criticising the manager in a recent interview.

Lee hit out at Pardew for being "too hot tempered in matches", claiming that the former Palace midfielder "forgets how many substitutes are left".
