Ruckman Jarrad Redden has undergone further surgery on his left knee and will miss the remainder of the 2014 season.

High performance manager Darren Burgess said Redden’s rehabilitation hadn’t progressed as well as hoped and after another assessment of the knee it was decided further surgery was required.

“This is really disappointing for Jarrad, he’s been working really hard on his rehab but the knee simply hasn’t been progressing as we’d expected,” Burgess said.

Burgess confirmed the 23-year-old, who has played 15 games for Port Adelaide, had a posterior cruciate ligament reconstruction last night.

“The surgery went well and Jarrad will now undergo about three months of intense rehabilitation,” Burgess said.

“The aim is for Jarrad to have this surgery now so he can give himself the best chance of doing a full pre-season in preparation for 2015.”
