Wanderers boss Neil Lennon has been charged for misconduct in relation to media comments he made following the 4-3 defeat at QPR on Saturday.
Lennon criticised referee Darren Drysdale and said: "He is a disgrace, an absolute disgrace.
"I have not seen a more biased performance from a referee in a long, long time.
"He gave QPR everything he possibly could."
An FA statement read: "It is alleged his post-match remarks constitute improper conduct in that they allege and/or imply bias on the part of the match official, and/or bring the game into disrepute, in contravention of Rule E3(1)."
Lennon has until 6pm on Thursday to respond to the charge.
