Wigan chairman Dave Whelan has expressed his disgust at the behaviour of Antolin Alcaraz, who was handed a three-match FA ban on Tuesday for spitting at Wolves centre-back Richard Stearman.
Whelan branded Alcaraz's behaviour "totally unacceptable" and insisted he would back manager Roberto Martinez should he decide to take further action against the Paraguay international.
"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."
Alcaraz spat at Stearman towards the end of Wigan's 3-1 defeat at Molineux on Sunday, with the incident sparking a mass brawl between both teams.
Wolves manager Mick McCarthy confirmed that he received an apology from Wigan counterpart Martinez after the game, but also took the opportunity to repeat criticism of Alcaraz's action.
"What happened is unacceptable," McCarthy said. "I have spoken to Roberto and he apologised on behalf of the club. I don't think that is indicative of Wigan, of Roberto or Dave Whelan. They are lovely people, a lovely club, and I think he (Alcaraz) has just made a mistake.
"I don't know where it came from but he's made a stupid mistake and got punished with a ban, and we all think that is right. Personally, I'd rather have a smack in the mouth than be spat upon.
"It's the worst thing you can do to a fellow professional. He will be regretting it now and will have to take the consequences.''
