The Football Association has charged Newcastle United boss Joe Kinnear with using abusive and insulting words towards a match official during Saturday's 2-2 draw with Stoke City.
The 61-year-old was sent to the stands by Mike Riley after becoming annoyed by the decision to hand the Potters a free-kick from which they grabbed a late equaliser.
An FA spokesman said: "Newcastle United manager Joe Kinnear has been charged with using abusive and insulting words towards a match official.
"Kinnear was sent to the stands during Newcastle's match against Stoke City on 6 December after contesting the award of a free-kick.
"He has until 23 December to respond to the charge."
Kinnear failed to attend the post-match interviews but first-team coach Chris Hughton said: "I think it was for perceived comments, but from where I was, I certainly didn't hear anything. That's what I think it was for.
"One thing I can tell you is that it's a very, very emotional game, certainly at that stage of the game.
"The linesman had given a decision some four minutes before that, which having seen it again, is exactly the same as our thoughts were at the time, that it wasn't a free-kick.
"It was an old-fashioned shoulder charge, both players competing for the ball, and the free-kick was given.
"Some four minutes later, he give another free-kick in a similar position, which again, we felt wasn't a free-kick."
Kinnear is yet to respond to an improper conduct charge after branding Martin Atkinson a "Mickey Mouse referee" following his side's 2-1 defeat at Fulham last month.
