After his season-long ban from the NRL expired, Carney joined the Sydney Roosters for the 2010 NRL season.

In preparation for his comeback season, Carney bought a punching bag to exercise with.

He played his first game for the club against his old team the Atherton Roosters, in a pre-season trial in Atherton.

After playing all of his football at Canberra in the halfback position, he was shifted to fullback by Roosters' coach, Brian Smith.

After his début against the South Sydney Rabbitohs in a 36-10 victory, Carney was kept at fullback.

Only shifting back into the halfback position to cover injuries or representative absentees.

Until round 14 against the Melbourne Storm, when he was permanently switched to halfback, displacing captain Braith Anasta to lock.

His switch to the halfback position was very successful, with the Roosters undertaking a five-game winning streak soon after the move.

Carney formed an incisive attacking combination with his halfback partner Mitchell Pearce.
He was also a facilitator to his outside backs with Anthony Minichiello and Shaun Kenny-Dowall in particular showing increased productivity.

In addition, he had taken on the kicking duties for the Roosters scoring over 200 points.

In the regular season Carney finished second on the top-point scorers and goal-kickers lists.

He was named as the season's 'Dally M Medallist' for the NRL's best player.

Carney also won the Dally M 'Five-Eight of the Year' and the Provan-Summons Medal ('People's Choice') Award.

He suffered no serious injuries.

Carney dated Seven Network television presenter, Liz Cantor.
Their relationship didn't last very long and they soon went their separate ways.

At the end of his 2011 NRL season, he had played a total of 118 games, 115 at club level and 3 at representative level.

On 26 February 2011, it was “reported” that Carney would face a low-range drink driving charge.
The Sydney Roosters confirmed that they would stand-by him through this indiscretion.

Just over a month later, Carney was found to be involved with Anthony Watts, when he was drinking on 16 April 2011.

Following the second incident in three-months, NRL management stood Carney down from the Roosters indefinitely.
He was subsequently required to receive treatment for his behavioural issues.

Carney returned to the NRL in a round 10 clash against the Cronulla Sharks at Toyota Park.

However in early August 2011, Carney, together with Nate Myles and Frank-Paul Nuuausala, broke a team agreement to not touch alcohol for two-weeks.
All three players were subject to disciplinary hearings.
