Muscat earned the hefty ban for his crunching tackle on Melbourne Heart player Adrian Zahra at the weekend.

Although Muscat may still play in the group stages of Victory's Asian Champions League campaign before hanging up the boots, it seems likely the 37-year-old has played his last domestic game after receiving the sentence from the A-League Disciplinary Committee on Thursday evening.

Melbourne Victory were given seven days to appeal the sentence, but accepted the Committee's decision within 30 minutes of hearing it.

Muscat was given a straight red for his 78th-minute challenge on the diminutive Zahra in last Saturday's dramatic 2-2 Melbourne derby, a tackle that saw the young midfielder tossed into the air before hitting the turf in agony.

Fortunately for 20-year-old Zahra, he has escaped without needing surgery to his knee, although he still suffered damage to every ligament in the joint without any of these tearing and will miss the rest of this season.

The Victory skipper had already expressed his remorse, saying he expected to receive such a lengthy sanction.

"I was prepared to accept whatever ban came my way," said Muscat in a media release.

"While I was relieved to hear Adrian's injuries weren't career-threatening, I'm still bitterly disappointed by my actions and I wish him a speedy recovery."

Speaking the day after the incident Muscat apologised for his actions, saying that mistiming the tackle to such a degree may be an indication the game is getting too fast for him.

On Thursday evening, Muscat said he would use the period away from the game to consider his options ahead of the Champions league campaign.

"I haven't really given any thought to my future," Muscat said. "My focus over recent days has been on Adrian Zahra and I was pleased to be able to personally apologise to him on Monday – which thankfully he accepted.

"My actions warranted a lengthy suspension and that's what has eventuated, so now I have to sit down with a variety of people and work out where we go from here."

Muscat finishes his A-League career having made 121 appearances for Victory and scoring 28 goals. He has also received 40 yellow cards and five red cards, although his last one may his most famous.

In times past, Muscat has seriously injured Craig Bellamy and Christophe Dugarry, the latter during a friendly clash for the Socceroos with France in 2001.

Muscat also injured Charlton's Matty Holmes in 1998, forcing the player to have four operations on his leg after it was initially feared it would have to be amputated.

Holmes later took Muscat to court where he received a settlement of GBP750,000 in 2004.
