Aitken came from the field midway through the first half of his side’s 18-14 loss to Cronulla last week.

He’s now facing an extended stint on the sidelines with what’s been described as a hamstring tendon injury.

“Euan suffered a hamstring injury against the Sharks and obviously didn’t finish the game,” Pickworth said.

“Scans over the weekend showed a decent tendon injury which is a little bit unusual so we’re still going through the process of establishing the best course of action and prognosis.

“We’re consulting a few different hamstring experts both in physiotherapy and rehab training so the return to play time frame for is still a bit unknown at the moment.

“Clinically he’s not looking to bad so hopefully he’s back on the field sooner rather than later.”
