Youngster Hugh Roach has vowed to seize his chance as the Waratahs' latest starting hooker after the suspension of Tolu Latu.
The 22-year-old is expected to be thrown into action for the Super Rugby defending champions with incumbent hooker Latu banned for four weeks for a dangerous tackle and Wallabies hooker Tatafu Polota-Nau (concussion) still being rested.
The Waratahs flew out yesterday for their two-match tour of South Africa with uncertainty hanging over the makeup of their team to face the Lions in Johannesburg on Sunday.
They are expected to appeal against the suspensions of Latu and lock Will Skelton (two weeks) on Monday for their tip tackle on All Black lock Sam Whitelock in Saturday's win over the Crusaders.
While Latu stayed behind, Skelton was travelling with the team, indicating they believe an appeal may clear him to play in one, or both, matches against the Lions and Cheetahs.
