Berisha was at the centre of a confrontation between players, coaching staff and officials after netting a late winning goal in Brisbane's 2-1 victory over Sydney on Saturday.

After the final whistle the Albanian removed his shirt and gestured toward Sydney's Pascal Bosschaart, appearing to suggest the two should settle any differences in the tunnel.

Berisha has now been given a one-week ban with a further week suspended, to be enforced in the case of a future transgression.

But mystery surrounds what happened after the final whistle when Postecoglou claims he was told by match officials that Berisha would be booked, effectively ending any further action.

A yellow card would mean the referee had dealth with the situation, denying the FFA any opportunity to intervene, as happened with former Newcastle Jets star Joel Griffiths when he hit a linesman.

Postecoglou says he saw the officials write Besart's booking on the official matchday teamlist - but it was later erased...and he doesn't know how or why.

"The facts are that directly after the incident the four match-day officials came up to me and said they were cautioning Besart, they saw everything and they deemed it should be a yellow card offence," he said. "They wrote it on the team sheet.

"Something's happened after that that's made them scrub it. It's been sent to match review panel, maybe that's why, because they can actually sit down and watch the video evidence."

Postecoglou questioned the process that led the FFA to hand down the suspension, after the referee and his assistants deemed a yellow card to be sufficient punishment at the time.

"The match review panel come back with nothing, so then it's referred to another party," he said.

"His offence is deemed to be more serious than players who have found guilty of betting on football ... players in a physical confrontation with officials after a game ... coaches questioning the integrity and character of referees.

"He had 30 seconds where he let his emotions run away with him and did something really silly which we were disappointed with, and he's apologised for.

"From my point of view, it would have been dealt with accordingly with some sort of reprimand against him."

The club now has to consider whether to appeal the one match ban, but delaying that decision until next week will allow Besart to play against third-place Melbourne Heart this weekend.

Either accepting the decision or a failed appeal would mean he then misses the following week's game against Newcastle Jets, although Postecoglou says he's ready to accept his striker's ban.

"It's been a distraction to myself," admitted Postecoglou. "But at the end of the day we've got a game in 24 hours time. The players trained well this morning and they're ready for it.

"I'm disappointed with the way it's gone, but I guess the decision's been made."

"I think from what I understand, obviously it's a club decision, not my decision ... we've got seven days to reply to it and come up with what we think we should do. My inclination is not to appeal.

"As I sit here now, I don't think it's smart to appeal."
