Richmond has sought permission from the AFL to have three recently-delisted players join pre-season training this week.

The Tigers have invited Cameron Wood (Collingwood), Orren Stephenson (Geelong) and Josh Toy (Gold Coast) to try out, after they were delisted by their clubs.

Wood, a 25-year-old, 204cm ruckman, has played a total of 64 AFL games, 16 with Brisbane from 2005-07, and 48 with Collingwood from 2008-12.

Toy, 20, spent two seasons with the Gold Coast Suns and played 13 games.

Stephenson, 30, played eight games as a ruckman for the Cats in 2012, after being a key member of three consecutive premierships with North Ballarat, in the VFL, from 2008-10.

Former Tiger rookie-listed small forward Addam Maric has already accepted an invitation to train with the Club.
