Irish striker Roy O'Donovan has been given an eight-week ban for head-butting, one of the longest suspensions ever handed out by Australia's A-League.

The 30-year-old, who plays for Central Coast Mariners, was cited for his attack on Wellington Phoenix player Manny Muscat over the New Year period.

O'Donovan pleaded guilty to violent conduct. Muscat was earlier banned for two matches for his part in the confrontation.
