Manchester United striker Robin van Persie will miss up to six weeks after suffering a sprained knee against Olympiacos, the club announced.
He was carried off on a stretcher after scoring a hat-trick during United's 3-0 victory over Olympiacos.
Van Persie was originally supposed to miss one game -- Saturday's game against West Ham -- but will now also miss the team's Champions League double header against Bayern Munich in addition to several Premier League matches.
Van Persie missed about three months of action earlier in the season with a thigh injury.
"We're getting Robin re-scanned again today,"manager David Moyes said, via the Daily Mail. "We're just not quite conclusive on everything we've seen yet. We want to just check that out and be sure. He won't be available for (Saturday's) game (against West Ham). But we'll try to give you some update when we can on the outcome of it."CREDITOR: Champions League draw: Bayern, Real Madrid, PSG, Barca avoid each other in quarters
