The Sydney Roosters have signed talented outside back Dale Copley from the Broncos it was announced by the club on Monday.

Copley and the Roosters reached agreement overnight on a three-year contract that brings the 24 year-old to the Sydney club with immediate effect through to the conclusion of the 2018 season.

Roosters recruitment manager Peter O'Sullivan believes Copley will be a valuable asset for the Roosters moving forward.

"We see Dale taking his game to the next level here at the Roosters, and with his signature being sought by a number of clubs, we are pleased to have secured his services," said O'Sullivan.

"A member of Queensland's emerging Origin squad, Dale is a tremendous finisher, blessed with wonderful footwork and a natural try-scoring ability. There's no doubt that he will add some terrific depth to our outside backs, and we look forward to watching his game develop in the coming seasons," he added.

Since making his NRL debut in 2009, Copley has played 72 top grade games, scoring 31 tries.

Broncos CEO Paul White said it was difficult to release a player who had been at the club since a young age.

"The last month has not been easy for Dale, but the club and his management have remained in constant contact during this period to allow the best outcome for all and not put unnecessary pressure on the player or the process.

"I have told Dale he is held in the highest regard by all at this club as both a person and a player.

"He leaves with our blessing and support, and we hope there is an opportunity for him to one day be a part of the club again.
