The Melbourne Rebels have named their team to play the Waratahs at at AAMI Park on Friday with Nick Phipps and Luke Jones both returning to the starting side.
James O'Connor was unable to return early from injury; after the decision was made by the medical staff not to risk the 23 year old.
Rebels High Performance Manager, Mark Andrews said the risk was too great at this early stage.
"James was desperate to play, which was admirable. However it would not be in the team's or player's best interest to risk further damage when the injury is a significant one, and has not fully healed."
