The Sydney Roosters have signed Parramatta five-eighth Daniel Mortimer on a two-year NRL deal, potentially filling the void left by Todd Carney's departure.

The 22-year-old Mortimer, a grand finalist in 2009, was granted a release by the Eels, having been used by new coach Steve Kearney in only nine first grade games in the 2011 season.

Roosters recruitment manager Peter O'Sullivan believed Mortimer would prove a useful asset.

"Daniel suits the Roosters' style of playand with his ability to play five eighth or halfback, we see him playing a key utility role, adding great depth to our halves alongside the likes of Braith Anasta and Mitchell Pearce," said O'Sullivan.

"Daniel is widely regarded as a quality person on and off the footy field and we are looking forward to watching him develop as part of our team over the coming seasons."

Carney, who won the Dally M Medal after an outstanding 2010 season, was released for disciplinary breaches this year.
