Hat-trick hero against Olympiakos, Man United striker Robin Van Persie was stretchered off towards the end of the vital 3-0 win.
David Moyes had earlier claimed the Dutch striker had picked up a ‘knock’ but Moyes today confirmed Van Persie was going for another scan.
Van Persie will miss Saturday’s Premier League clash with West Ham and is considered a major doubt for the derby against Manchester City on Tuesday.
One of United’s forgotten men Shinji Kagawa or Javier Hernandez could be handed a rare start.
