Manchester United boss Sir Alex Ferguson has been told by the Football Association not to comment on defender Patrice Evra's racism claims.
Evra claimed he was subjected to abuse by Liverpool's Luis Suarez after Manchester United's 1-1 draw last Saturday.
The FA have now opened their investigation and spoke to Evra, but for the duration of the case, they have told Ferguson not to speak.
"The FA interviewed Patrice yesterday and have sent us a directive today saying not to discuss it while the investigation is going on," revealed the Scot.
"I have got plenty to say on the subject but I suppose I will have to adhere to what they are saying. I would like to say something about Pat in this particular instance but let them get on with their investigation."
Earlier this week, Liverpool manager Kenny Dalglish said that his club was "100% behind" Suarez.
