Reds winger Lachie Turner has been ruled out of Super rugby for the next five weeks after he underwent surgery on his ankle.
The former Waratahs wingers had surgery to clean up up loose cartilage in his ankle on Tuesday and is not expected back five weeks.
Turner has been a regular starter for the Reds in 2014 but missed last weekend's match against the Western Force due to an ankle complaint.
He is expected to be available for selection in time for the Reds' home clash with the Rebels in Round 14.
Reds head coach Richard Graham said the absence of Turner's experience in the back three would be a loss for the team.
"It is disappointing to lose Lachie (Turner). He has been playing very well and has offered some versatility among the back three," Graham said.
"He suffered a fracture and dislocation of his ankle in early 2013. Unfortunately some cartilage has come loose in the same ankle and is irritating the joint."
Turner joins several other Reds in rehabilitation, including Liam Gill (hamstring-five weeks), Ben Daley (knee-two weeks), Samu Kerevi (ankle-two weeks), Chris Kuridrani (ankle-five weeks), Dom Shipperley (hip flexor-two weeks) and Aidan Toua (pectoral-12 weeks).
"We have a few boys out with injury at the moment, but we are fortunate to have Chris (Feauai-Sautia) and Saia (Fainga'a) returning from injury and available for selection this week. "
"We've obviously still got some depth within our squad, with a lot of the younger group having been exposed to the Reds A program," Graham said.
