David McDuling will start in the second row for the Waratahs in Saturday's clash against the Sharks in Durban, with Will Skelton to remain sidelined.
Skelton continues to experience discomfort with a hamstring injury, paving the way for McDuling to get a start against his former team-mates when he runs out at Kings Park.
Waratahs head coach Daryl Gibson is excited to offer McDuling the opportunity to step up into the role.
“We are excited for David who has earned the chance to start after his performance as a finisher in recent weeks," said Gibson.
"It is a great opportunity for him to go up against his old team."
McDuling is pleased to return home to Sydney to play with the Waratahs this season, and is looking forward to running out against his former team-mates.
"They (the Sharks) will be confident after winning that game last week against the Brumbies on tour. It’s their first home game so they will be looking to put on a good show for their fans,” he said.
"I always look forward to playing, especially with my ties to Durban and the Sharks it does make it a little bit special.
"Everyone enjoys playing against people they know, which is the same in the Australian derbies – you want to get one up over your mates.
"“For me it is another great opportunity to pull on a Waratahs jersey, play at a great stadium against a great team."
Wallaby scrum-half Nick Phipps returns to the Waratahs run-on side after he was forced to miss round two with an ankle injury.
