Defender Jake Kolodjashnij is back in the main training group after a frustrating pre-season.

Kolodjashnij battled glandular fever then groin pain during the summer, but he's now recovered from those ailments.

"Jake's going really well," Cats physio Mark Young said on the latest episode of the GMHBA Health Report.

"He's had a frustrating run in rehab.

"He's now joining in full training and we're now looking at a game in the near future.

"So the signs are good there."

Young also speaks about Nakia Cockatoo, Cameron Guthrie and Jamaine Jones.
