Roosters' premiership player Cam Richardson.

The Kangaroos announced this afternoon they had delisted Richardson and Ben Speight.

Both were on the Kangaroos' rookie list.

This is the second time Richardson has been delisted by the Kangaroos - he was axed from the senior playing list last year, but with the guarantee of being re-added to the club via last year's rookie draft.

The 25-year-old has played eight AFL games, all in his debut season in 2011.

He struggled to break into the Kangaroos' line-up last year after hip-surgery in the off-season lead-up but has been a solid contributor the past two season with North Ballarat, the Kangaroos' Victorian Football League partner.

Richardson was drafted to North Melbourne, via an on-trade from Gold Coast Suns, after a stellar effort in the Roosters' 2010 VFL premiership year.
