The GAA's Central Competitions Control Committee [CCCC] will review Séamus Flanagan's collision with Waterford's Stephen Bennett when they meet this week.
RTÉ Sport understands no decision has yet been reached on the incident, which saw the Limerick full-forward make a high challenge late in the first half on the Déise man, his shoulder colliding with Bennett's jaw.
If punished, Flanagan will become the third Limerick player, after Kyle Hayes and William O'Donoghue, to be retrospectively banned this year.
The flashpoint sparked some debate with The Sunday Game analyst Liam Sheedy saying Flanagan was a "very lucky man" to avoid a red card. "That connection is high into the face," he said.
Anthony Daly added that the four-time All-Ireland winner "wasn't looking at the ball".
A full-blooded contest saw a second-half melee involving both Limerick and Waterford players after Gearóid Hegarty barged Conor Gleeson with a late shoulder.
There was a subsequent coming together that involved players and backroom officials, with Hegarty - dismissed on a second yellow card - appearing to be struck on the chest by a member of the Waterford backroom team.
Speaking to RTÉ Sport after the match, Limerick manager John Kiely said: "Whatever about Gearóid and his engagement with the Waterford player, I didn't see that, so I can’t comment on that, so I’m not going to comment on the yellow card.
"The piece after that was very disappointing and hopefully it will be dealt with accordingly."
Waterford still in it despite Limerick being on top and Seamus Flanagan lucky to still be on the pitch is the HT verdict of the RTÉ panel
