Manchester, England (SportsNetwork.com) - Manchester United manager David Moyes revealed on Friday that winger Nani is facing a few weeks out because of a hamstring injury.

The Portugal international has been battling the problem for the past few weeks and has been an unused substitute in two of the club's last three matches.

"Nani has got a hamstring injury and we were worried about that. It's worse than we hoped so that might well keep him out for a few weeks," Moyes said at a press conference on Friday.

The 27-year-old has appeared in eight league matches for the Red Devils this season, and he joins Michael Carrick and Robin van Persie on the sidelines, while striker Wayne Rooney is battling a groin strain that could keep him out of Saturday's match with West Ham.
