Cronulla have stood down halfback Brett Seymour from all commitments with the NRL club pending further investigation into an alleged alcohol bender on Sunday evening.

Seymour is under investigation following a drinking session that started last Sunday afternoon with club coach Ricky Stuart and teammates at a local pub.

While Stuart and several others went home early, Seymour reportedly partied on until his night ended after midnight with the halfback ejected from 2230 Lounge Bar.

News Ltd said sources gave conflicting reports about his behaviour with some saying he'd thrown pizza and abused patrons while others insisted he would be cleared of wrongdoing.

It's not the first time Seymour has been accused of alcohol-related indiscretions. He was sacked by the Brisbane Broncos in late 2006 for an incident at the Regatta Hotel.

Sharks chief executive Tony Zappia said the club would fully investigate the latest claims and were attempting to access CCTV footage.

With current events in mind, it would be an understatement to say we are disappointed Brett has put himself in this position," said Zappia in a statement.

"He is obviously slow on the uptake, showing a lack of responsibility to himself, his teammates and to the club.

Seymour's incident came less than a week after the NRL stood down Manly's Brett Stewart for four weeks for his public drunkenness at the Sea Eagles' season launch.

Sydney Roosters hooker Jake Friend is another to misbehave after he was caught drink driving at three times the legal limit after a club booze session last Monday night.

He has been fined $10,000 by the club and ordered to undergo education and counselling.
