DANIEL Roach - the son of league legend Steve "Blocker" Roach - has turned his back on rugby union, walking out on New South Wales to link with the Sharks. The talented young prop will now follow in his famous father's steps, carving out a career in rugby league. The former Australian Schoolboys union star knocked back an offer from his father's Wests Tigers for a chance to play under Australia coach Ricky Stuart at the Sharks. Roach is expected to begin training with the Sharks on Friday, on a one-year deal, after officially requesting a release from the NSW Rugby Union last week. The teenager's switch is sure to leave the Waratahs red-faced, with the emerging forward considered by many astute judges to be a future Australia prop.
