Wigan manager Paul Jewell is to take internal action against Lee McCulloch after the midfielder was caught punching Sheffield United captain Chris Morgan.
Morgan sustained cuts above and below a swollen right eye after McCulloch lashed out in the closing stages of the Latics' 1-0 defeat to the Blades on Saturday.
McCulloch pleaded guilty to a violent conduct charge handed out by the Football Association and now faces a three-match suspension.
The Scotland international misses Saturday's game with Chelsea at the JJB Stadium, as well as the Boxing Day match at Manchester United and the December 30 clash at Watford.
With Senegal striker Henri Camara today ruled out for six weeks with a medial ligament knee injury, McCulloch's absence - as he can also play in attack - comes at a crucial time for Jewell.
'Lee fully deserved to be charged. There was no escape,' said Jewell.
'It was all very well for Chris Morgan to say he shouldn't have been charged, but it was right he was.
'It was a silly thing to do, irresponsible, and although it was out of character, we'll be taking internal action against him.'
Jewell is further angered by the fact the FA took no action with Juan Pablo Angel after the Aston Villa striker elbowed Morgan in an incident a few days earlier as blatant as that involving McCulloch.
On that occasion referee Mark Halsey saw what unfolded, yet took no action, which meant the FA were unable to act retrospectively.
'It's the inconsistency of the law that drives me up the wall,' added Jewell.
'Everyone could see Angel elbow Morgan, yet nothing happened as the referee saw it. What a load of nonsense that is.
'I saw it and everybody else saw it. It was a bad challenge, but because the referee has dealt with it, nothing gets done.
'Now I'm a believer in right and wrong, and I thought they were both wrong.
'I can show you plenty of examples where players at top clubs have done things wrong, yet got away with it, with the ref only giving them a yellow card when it should have been red.
'The FA say they can't referee a game retrospectively, but if you are wrong and the evidence is there then you take action.'
Jewell, meanwhile, has warned Arsenal they can forget trying to land Leighton Baines on the cheap.
The Gunners were this week linked with a £4million transfer window move for the England Under-21 international.
Yet Jewell said: '£4million won't get Leighton Baines that's for sure.
'If he is being talked about as a future England full-back, then you can't get him for that.
'I'll never stop a player going to a top-four club, but I will at £4million. That's not on.
'Right now I've had no contact with Arsenal, but I can guarantee he will not be going for that amount of money.
'Obviously, we don't want to lose any players. Leighton is a very sensible lad, and I think he is a better off here at the moment.'
