Wigan chairman Dave Whelan has blasted Antolin Alcaraz for spitting at Wolves defender Richard Stearman.
Paraguay international Alcaraz spat at Stearman during the closing stages of Wigan's 3-1 defeat to Wolves at Molineux on Sunday to spark a brawl involving several players from each team.
Referee Lee Probert missed the incident, but the Football Association decided to take action against Alcaraz.
Alcaraz has accepted his FA charge and will serve an automatic three-match suspension, but he could face further disciplinary action from Wigan, with Whelan insisting he will back any punishment dished out by Latics boss Roberto Martinez.
"That sort of behaviour has no place in football. It has no place in society," Whelan is quoted as saying in The Sun.
"It is disgusting, a horrible thing to do and I was shocked.
"I will back whatever punishment the manager decides to impose.
"I cannot tolerate this sort of thing and it saddens me that a Wigan player is alleged to have done it. It is totally unacceptable."
Meanwhile, Wolves captain Roger Johnson admits Alcaraz deserves everything he gets for committing the worst thing you can to do to a fellow player.
"It's the worst thing a footballer can do to a fellow professional," noted Johnson.
"It's dirty and he deserves everything he gets. It's there for everyone to see - he spat on him.
"He'll be regretting it now and he's got to pay the consequences."
