The case has been referred directly to the A-League's disciplinary body, a body that hears the competition's more serious cases such as the eight-match ban given to Sydney FC defender Tiago Calvano in 2013 for grabbing a referee.
There is no upper limit on the tribunal's punishments, and it has tended to come down heavily on instances of serious physical misconduct.
The Mariners declined to comment yesterday, waiting for the case to run its course, but are certain to be without O'Donovan for Friday's trip to Melbourne Victory and several weeks beyond that.
It's likely the club will seek to claim mitigation from Muscat's elbow on O'Donovan, and the striker himself gave a very grudging apology to Fox Sports at the end of last week, lamenting the way Muscat had gone to ground and claiming the defender deserved "an Oscar" for it.
"I've got elbowed in the face not once, not twice, and the referee hasn't seen fit to react to that and book Manny Muscat," O'Donovan said. "I walked away and had a player run into my direction, I leaned my head in and I've reacted to it. He's gone down like a movie star there. He should get an Oscar for that. He timed it perfectly.
"(The referee) felt there wasn't enough force behind what I did. I got yellow-carded and nobody got hurt. Manny played out the rest of the game, he didn't have a scratch or a bruise. We shook hands after the game ... and I'm the only one that has any wounds from the whole event."
