Reds fly half Quade Cooper has extended his contract with the Queensland Rugby Union until 2015, keeping him playing Super Rugby in Australia until the next Rugby World Cup.

The 35-test veteran admitted Saturday he was out celebrating his new deal on the night he and Kurtley Beale - both players are injured and unavailable for the test against Wales - were allegedly involved in an altercation outside a Brisbane bar.

Cooper said that he would not comment on details of the allegations because an Australian Rugby Union investigation was ongoing.

The 24-year-old Cooper was integral to the Reds' Super 15 championship season in 2011 but struggled in the World Cup, ending with a serious knee injury and dubbed by the local media as "Public Enemy No. 1" in New Zealand, where he was born.

New Zealand beat Australia in the semifinals and then edged France in the final.

"I'm in a good place at the moment, and I'm enjoying where the Reds are going as an organization and as a team," Cooper told Fox Sports News.

"We've got a bright future ahead and hopefully a few more titles in the next few years."

The re-signing of scrumhalf Will Genia had a role in Cooper's decision to stick with the Reds despite interest from foreign and interstate clubs and rugby league.

Cooper, who has only played 120 minutes of rugby for the Reds this season, has been in trouble with the ARU over off-field issues in the past, but attempted to play down the latest episode.

"We were doing what young blokes do," he said. "We were playing a bit of pool and it escalated from there."
