Sydney veteran Peter Everitt has raised the possibility that team-mate Barry Hall's recent poor on-field behaviour may be linked to his desire to quit the AFL and take up boxing.

Hall was a talented junior boxer in Victoria before quitting the sport to pursue his AFL career but is considered a future boxing star in waiting.

Even Australia's most respected boxing trainer Johnny Lewis says Hall has the talent to be one of the country's best boxers.

Only last year, leading Australian fight promoter Angelo Hyder said Hall could make as much as $10 million from a successful boxing career but at 31 years of age he is running out of time to follow Anthony Mundine's lead and make the successful transition from football (in Mundine's case, rugby league) to the boxing ring.

Hall has been stood down by the Swans indefinitely for 'personal reasons' after his one-match suspension for attempting to strike Collingwood's Shane Wakelin on Saturday night - which came in just his third match back following a seven-match ban for the vicious left hook he landed on the jaw of Eagles defender Brent Staker behind play in Round 4.

Everitt, a former team-mate of Hall's at St Kilda as well as Sydney, said Hall may be weighing up in his mind whether to quit the AFL in favour of boxing.

"Everyone knows he has got passion if it is now for boxing or if it is going to be in two or three years," Everitt told Fox Sports News on Tuesday morning.

"The question for Barry is - is it now or is it going to be in a few years."

"I think that is what everyone is going to be asking but the only person who can answer that is Barry or is it (related to) personal issues."

Everitt said the players were doing everything they could to support Hall saying he hoped his problems were related to personal issues which could soon be sorted out rather than the prospect of quitting the game to take up boxing.

It is also believed that Hall's current problems involve two women - one being his on again, off again girlfriend Kylie Stray and the other being Melbourne bikini model Tahli Greenwood, who he has also been linked to.

Swans coach Paul Roos said on Monday that Hall - the club's 2005 premiership captain and leading goalkicker in the past six years - would not play again until given the all-clear by the club's psychologist.

"We're not sure how long before he'll play again," Roos said of Hall.

"We, as a club, can't put Barry in a position that at the moment he is not capable of handling."

Hall is contracted to the Swans until the end of next season which means that if he were to remain with the club until the end of the 2009 season that would still leave him free to pursue his boxing career at 32 years of age.
