Sam McClure has provided some insight into Joel Selwood’s struggles so far this year, revealing he’s dealing with knee tendinitis.

The Geelong skipper has averaged 21 disposals this year, the lowest since his first season of footy back in 2007.

“Joel Selwood has been down on form. His last four weeks – 18 disposals, 17, 22 and 21,” McClure told SEN’s The Match Committee.

“Whether Joel or Geelong are willing to admit this or not, he’s injured. He’s got knee tendinitis and he’s been struggling.

“He’s been barely able to train in the last month or so. We know he missed two weeks earlier in the season with a leg problem, I think it was a similar injury.”

Former Western Bulldogs coach Terry Wallace admits knee tendinitis is a tough injury to recover from and isn’t a matter of just taking a month off.

“It’s a difficult injury because what you can do, if you off-load them hoping it’ll get better, you actually come back and as soon as you put the pressure back on, you’re quite regularly back in the same spot as you were so you’ve achieved nothing,” Wallace said.

Geelong has the bye this weekend before travelling to the Adelaide oval to take on the Power.
