Sharks assistant coach Warren Whiteley said newly recruited loose forward Vincent Tshituka is coming along well for them.Tshituka, who made the move from Johannesburg to Durban, hasn't cracked the Sharks' match-day 23 as head coach Sean Everitt has preferred Dylan Richardson, James Venter, and Phendulani 'Phepsi' Buthelezi as his starting loose forwards with Sikhumbuzo Notshe coming off the bench.READ HERE | Familiar faces Wayne Barnes, Angus Gardner to ref Bok Tests on end-of-year tourThat's some competition to deal with, but Whiteley said Tshituka has been training with them in Dublin as they prepare for their United Rugby Championship (URC) clash against Leinster on Saturday."Vince has been training with us and he's been looking good and strong," Whiteley said.READ | Bok lock Eben Etzebeth set for Sharks bow on 15 October against Glasgow "He had his first 15-on-15 session as he recovers from injury, so I'm pretty sure it won't be too long before he's back on the field."
