The Sunday Game panel took a dim view of an incident involving Tyrone wing-back Tiernan McCann in his side's Ulster SFC semi-final defeat to Donegal on Saturday.
While trying to wrestle the ball back from Donegal defender Stephen McMenamin, who was on the ground, McCann appeared to reach into McMenamin's mouth and also stood on the Donegal defender's neck in an incident that went unpunished by referee David Gough at the time.
"This is despicable really," said 10-time All-Ireland winner Valerie Mulcahy. "Putting the two fingers into the mouth, and then to follow that with a stamp of the foot onto the back of his neck. You don't want to be seeing that."
Former Kerry defender Tomás Ó Sé said he didn't believe the contact was accidental.
"He knew exactly what he was doing, the hand is going into it. Somebody said he was being pushed and that the boot was part of that but he knows exactly where the body is underneath him.
"I think it's disgusting. There's no defending it whatsoever."
McCann can expected to face a ban for his actions.
"It's totally unacceptable," added former Dublin star Ciarán Whelan. "There are incidents in games where fellas can lash out out of frustration but that's crossing the line.
"You can't put your hands in there."
