Green Room Sports Management has announced the addition of Kevin Sinfield MBE to its rugby portfolio.
The 35-year-old, who retired from all forms of the game in May, switched codes from league to join union side Yorkshire Carnegie last November after leading the Rhinos to the treble.
Alongside current rugby union names including George Ford, Ben Youngs and Jonathan Joseph. Sinfield is the first player famous for his rugby league exploits to join the agency, having recently retired as one of the most successful players in Super League history.
In his 19-season professional career in rugby league, Sinfield led Leeds to seven Grand Final victories, back-to-back Challenge Cup triumphs and three World Club Challenge successes. He scored 3,967 points from 521 appearances for Leeds and won 40 caps for England and Great Britain, captaining his country in the 2013 World Cup, while his career total of 4,231 points, from 569 matches, put him third in the all-time list, behind Neil Fox and Jim Sullivan.

Richard Wilks, managing director at Green Room Sports said: “The goal has always been to deliver the best management to world-class rugby players, on and off the pitch, as well as to identify, nurture and guide the best up and coming talent.
“Kevin has had an outstanding career, one I’ve admired as a fan of rugby league. He is bright, engaging and a born leader and we are excited to be able to support him in the next stage of his career.”
