Controversial Brisbane Lions star Brendan Fevola may have played his last AFL match after a league and police investigation was launched into an alleged incident outside a Queensland bar at the weekend.

Fevola, at the centre of at least six major off-field incidents through a turbulent career, has this time been suspended indefinitely by the Lions for an alleged incident where it is claimed he indecently exposed himself to a married mother of four outside a bar.

It's understood Fevola asked the woman, who was at the function with her husband and two of her four children, out to his car where the alleged incident occurred. The husband lodged an official complaint to the club. Other Lions' players were in attendance at the event and have been questioned.

Fevola was suspended indefinitely by the Lions on Wednesday.

Asked if Fevola, having just completed a disappointing first year with the Lions after he was effectively sacked by Carlton this time last year, had breached his contract, Lions chief executive Michael Bowers somewhat poignantly replied: "We need to get all the facts."

AFL operations manager Adrian Anderson said the priority was to get "the facts right" before punishment would be considered.

Fevola is categorically denying the claims that he behaved inappropriately. His management company last night urged people to prejudge him on this matter.

If Fevola is deemed to have brought the game into disrepute, he may not only be sacked but could be derigistered by the AFL - the same punishment Ben Cousins received in 2008. It's questionable whether another club would want him.

Former Carlton coach Denis Pagan, who worked hard during almost five years in charge of the Blues in trying to keep Fevola in line, was disappointed to hear of the latest allegations.

"It's very unfortunate. I feel for everyone concerned," he said.

"I don't know the facts but there are no winners in an incident like this.''

Fevola's first AFL coach, David Parkin, has said he and the Blues had failed the forward by not "modifying" his behaviour early in his career and "he has maybe been able to get away with things that he shouldn't have".

Ridding themselves of Fevola could help the Lions on several fronts.

They have major salary-cap constraints, due in part to Fevola's hefty deal which next year will see him pocket more than $700,000. The lack of cap space has played a part in the defection of blue-chip midfielder Michael Rischitelli to the Gold Coast Suns, and threatens the future of out-of-contract stars Jared Brennan, Simon Black and Luke Power.

At 29, Fevola's increasingly fragile body also makes a liability, with a serious groin injury forcing a premature end to his season in round 18. He played 17 matches and kicked a modest 48 goals.

The acquisition of Fevola last year, after his antics on Brownlow medal night prompted Carlton to finally trade him, split the Lions' faithful. This time sponsors and members may turn their backs on the Lions completely if he stays, a major worry for a club that is expected to post a $2 million loss this year.

If Fevola was sacked, it would heap even more embarrassment on coach Michael Voss, who has regularly been criticised for topping up his list last year with the likes of senior players Fevola, Andrew Raines, Xavier Clarke and Matt Maguire - unwanted by their former clubs.

The initial bungled deal by Voss where a trade with the Blues for Fevola in exchange for premiership forward Daniel Bradshaw, a respected clubman, and Rischitelli fell through eventually meant they lost the uncontracted - and crest-fallen - Bradshaw to the Swans for nothing while a shocked Rischitelli clearly wanted to flee once this season was done. To Rischitelli's credit, he had a stellar 2010 and is tipped to win Thursday night's best-and-fairest count - a function Fevola has now been banned from.

Fevola has been the subject of a series of false allegations through this career, but his shame-file list is too long to ignore.

He had already been embroiled in Lara Bingle nude-photo scandal this season, having also finally come clean on his gambling problems, admitting the extent of losses could top $200,000. He also revealed wife Alex and their children had moved back to Melbourne.

Fevola, the No.38 pick in the 1998 national draft, was dumped by the Blues after a boozy night at the Brownlow medal count where he behaved inappropriately towards a young woman.

He was caught urinating on the front window of the Candy Bar in Prahran on the eve of the 2008 season and fined $10,000 by the Blues.

He was photographed in the middle of Federation Square in Melbourne drunk in a nightie wearing a dildo on "Mad Monday" after the 2008 season.

In 2006, Fevola assaulted a barman in Ireland during the international rules series. He was ejected from the team and sent home in disgrace.

In 2004, he was involved in an early-morning incident at Crown casino but no charges were laid.

In early 2001, he was accused of spraying a woman in the face with a fire extinguisher at Victoria University's student village, while in September of that year he was fined $8000 after allegations he and teammate Ryan Houlihan tried to steal jackets from a North Melbourne dry cleaners.

Fevola's management company, Velocity Sports, last night released a statement on behalf of their star client. It said in part: ''The Club has apparently received a complaint in relation to an incident which allegedly occurred at lunch time last Saturday. However, the details of the complaint have not yet been provided.

''Brendan will cooperate fully with any investigation that is determined to be necessary by Queensland Police or the AFL.

''He categorically denies any inappropriate behaviour in relation to the alleged incident. We encourage people not to prejudge this matter until it has been finally resolved and to respect Brendan's privacy in the meantime.''
