Sydney FC's Tiago Calvano will face an A-League disciplinary committee hearing over the serious charge of making contact with a referee.
The Brazilian grabbed the right arm of referee Peter Green just before his Sky Blues teammate Marc Warren was red-carded in the 25th minute of their 3-2 win over Melbourne Victory on Saturday night.
The hearing will be held next week, with Tiago in danger of spending a long stint on the sidelines.
Central Coast goalkeeper Danny Vukovic was banned for nine months in 2008 after hitting the arm of referee Mark Shield during the grand final.
Tiago was also cited over a separate incident in the 79th minute when TV replays showed he appeared to strike Archie Thompson in the face.
Also on Monday, the A-League's match review panel suspended both Warren and Adelaide United's Nigel Boogaard for one match.
Warren was sent off for dragging down Victory's Connor Pain as he sped towards goal.
Boogaard was marched in the 90th minute of the Reds' loss to Newcastle on Saturday for a tackle on Jets star Emile Heskey.
It was the fifth time Boogaard had received a straight red card, equalling the all-time league record of new Melbourne Victory coach Kevin Muscat.
