Ben Sigmund will miss Monday's visit to Melbourne Victory after Football Federation Australia surprisingly rejected a Phoenix appeal to overturn his red card from Saturday's controversial A-League game in Adelaide.
The Phoenix defender was sent off in the 77th minute after making light contact with Adelaide striker Jeronimo Neumann, who carried on his run before taking a dramatic tumble in the box.
But despite evidence to the contrary, the league's match review panel of Simon Micallef, Alan Davidson and Alan Contini last night determined there was "no obvious error" in referee Jarred Gillett's decision.
That also clears Neumann of any punishment for diving, with the panel ruling "there was no basis under the regulations to conduct a post-match review for possible simulation".
The Phoenix lost 3-1 and, rubbing salt into the wound, Phoenix captain Andrew Durante may also cop a fine for his explosive post-match interview.
The FFA will send the Phoenix a "please explain" note this week after the usually composed defender labelled Neumann a "cheat" and the referees "shocking".
Furious Phoenix fans will dip into their own pockets should Durante be fined for bringing the game into disrepute.
Supporters group Yellow Fever have set up a donations page on the website givealittle .co.nz, where fans can make a contribution towards a possible fine.
"He's just told it like it is," said Fever stalwart David Cross.
"He shouldn't get any fine. Jeronimo should be suspended for diving, Sigmund's card should be withdrawn, and the FFA should take this opportunity to come down hard on diving and accept that the referee had a bad night.
"But if Dura does get a fine we'll help him out."
Durante is not in danger of being suspended for the Victory game.
The previously unbeaten Phoenix ended round four in sixth place after Sunday's controversial match at Sydney's ANZ Stadium.
Sydney FC stars Alessandro Del Piero and Brett Emerton both scored in the 2-1 win over Perth Glory, who had Steve Pantelidis sent off.
Sydney also survived a late penalty shout, with Glory coach Ian Ferguson furious a handball was not called on Rhyan Grant in the 88th minute.
"I would like to get it clarified - what is a penalty?" Ferguson said.
