Manchester United have suffered another blow to their defensive plans as the FA decide whether to charge Nemanja Vidic with violent conduct while Jonny Evans continues to struggle with an ankle injury.
Vidic is facing trial by TV after appearing to slap Wigan centre forward Hugo Rodallega on Saturday.
Tempers flared when the striker clattered into United keeper Ben Foster in an attempt to win the ball.
Last night the FA confirmed that they will look at the incident and Vidic could face a three-match ban.
Meanwhile, it is understood that United are considering whether to send Evans for surgery after he limped off with a recurrence of an injury that has bothered him all season.
United can ill afford to lose either player as their other main central defender, Rio Ferdinand, is out with a thigh problem.
Referee Howard Webb did not see the Vidic incident at the DW Stadium but will be asked by the FA what he would have done if he had.
Rodallega certainly made the most of the incident and may even face sanction himself after appearing to shrug off Webb a little too vigorously as the official attempted to calm him down.
