Chelsea players including AshleyCole have been interviewed by the Football Association as part of its investigation into the club's allegation that referee Mark Clattenburg used" inappropriate language" towards John Obi Mikel.
Clattenburg has strenuously denied the allegation. With no FA verdict expected until later this week, he will not officiate for a fourth successive weekend - a situation he has welcomed, saying he does not want to take charge of any matches while the case is ongoing.
The FA has spoken to Clattenburg, Mikel, the assistant referees for the United game, Michael McDonough and Simon Long, and fourth official Michael Jones.
