Adelaide defender Josh Worrell will miss Friday’s pre-season clash with West Coast due to a left hamstring injury.

Worrell suffered the injury against Fremantle last Friday and had scans in Perth this week.

“The scans showed some damage but because it’s a reaggravation of the hamstring injury he suffered last month, it’s difficult to put an exact timeframe on his return,” Crows High Performance Manager Darren Burgess said.

“Josh has started the rehabilitation process and his return to play will be dependent on how the injury responds to treatment.”
