Adelaide United defender Antony Golec will not play this weekend as part of his penalty for a homophobic slur on Twitter against A-League referee Ben Williams.
Golec has received a three-match ban, which has been suspended for the second and third games.
He is not allowed to play in either United's A-League clash on Friday night or in the National Youth League fixture on Sunday - both against Gold Coast United.
A ban for the further two games will be triggered if Golec breaches the code of conduct again during the season or fails to undergo "appropriate counselling and education" by March 11.
"Adelaide United FC is tasked with ensuring that this is carried out in an appropriate manner," a Football Federation Australia statement said.
"Compliance with this requirement, and accordingly whether the two-match suspension will be triggered, shall be determined by FFA in its sole discretion."
Golec, 21, has apologised for his "foolish" Twitter posts about Williams, who came in for heavy criticism after issuing red cards to Melbourne Victory players Ante Covic and Matthew Foschini in the first half of the 2-2 draw with Brisbane Roar last round.
Golec has written a letter of apology to Williams, while Adelaide have warned the young defender his contract will be ripped up if he transgresses again.
