The Sydney Roosters have today announced the signing of Cooper Cronk on a two-year deal for seasons 2018 and 2019.

33 year-old Cronk is a two-time Dally M Player of the Year medalist and has played 323 first grade games since making his NRL debut with the Melbourne Storm in 2004.

"We are delighted to have secured the services of Cooper for the next two seasons," said Roosters Chief Executive Joe Kelly.

"Cooper has played the game at the highest level for a number of years and we are keenly aware of what he brings to the club. Together with the established leaders within our squad, we see him as a wonderful addition to our roster," he added.

Cronk expressed his delight to be joining the foundation club, saying: "The Sydney Roosters are a proud club with an esteemed history, and this is an exciting new opportunity for me."

"It marks the start of a new chapter for me both professionally and personally and I look forward to joining my new teammates and coaches, and immersing myself in the club's culture in lead-up to the 2018 season," he added.

The Australian representative will officially join the Roosters in early 2018 following his World Cup commitments.
