Emerging Geelong defender Jed Bews is closing in on signing a contract extension with the Cats.

Bews has enjoyed his best season at senior level this year establishing himself an important part of the side's defence, playing 16 games and averaging 12 disposals and three tackles.

He is set to come out of contract when the current season ends, however, the 23-year-old told the Geelong Advertiser he is close to putting pen to paper on a new deal.

“It’s close, very close,” Bews said.

“I’m not all that concerned about it. It will happen in the next few weeks, I am sure.

“We are working out the fine details.”

Following Bews' deal, Steve Motlop, Daniel Menzel and Tom Ruggles are the biggest names at the Cats yet to be signed beyond this season.

Promising youngsters Jake Kolodjashnij, Nakia Cockatoo, Brandan Parfitt, James Parsons and Sam Menegola have all recently signed contract extension with the Cats.

Bews has played 47 games with Geelong after being recruited in the 2011 draft as a father-son selection with pick No.86.
