Brisbane - Wallaby flyhalf Quade Cooper said on Saturday he had re-signed with the Reds for three years in a deal that will keep him in Australia until the 2015 Rugby World Cup.

"I'm just thrilled to have my future settled for the next three years," Cooper told Fox Sports television.

"I'm really enjoying my time here, I'm in a good place at the moment and I'm enjoying where the Reds are going as an organisation and as a team."

Cooper's announcement of signing an extended contract with the defending Super Rugby champions came after reports of a late-night incident in Brisbane on Thursday, which is being investigated by the Australian Rugby Union.

Media reports said Cooper and Wallaby team-mate Kurtley Beale were allegedly involved in an altercation with security guards after being asked to leave a hotel in the early hours of Friday morning.

Cooper confirmed on Saturday he was out with Beale celebrating his new Reds deal when there was an altercation outside the hotel.

"We were doing what young blokes do," Cooper said of the incident.

"We were playing a bit of pool and it escalated from there.

"We're both flyhalves so there's not going to be too much brawling."

Cooper said the risk of re-injuring his knee was too high by playing in the current three-Test series against Wales and he was targeting a Super Rugby return against the Rebels in Melbourne on June 29.

The mercurial Cooper ruptured knee ligaments in the World Cup playoff for third place against the Welsh seven months ago and has played only 120 minutes for the Reds in two matches since the surgery.

Cooper confirmed the news on Twitter, writing: Coz I love you all I let something slip. I'm staying with the QLD REDS for another 3years :) happy times. Now love me back coz I love you :)

With announce officially Monday. But iv agreed to remain in QLD simply coz I love the team the fans n this is the best state in Aus :)
