GEELONG has made one change to its team ahead of Saturday's blockbuster with Carlton at the MCG at 7.25pm.

Jake Kolodjashnij returns to the side after completing the AFL's concussion protocols replacing fellow defender Jed Bews who has been managed.

The Round 18 clash promises to be a terrific contest with just one victory separating the top-of-the-ladder Cats from the fifth placed Blues.

Geelong has won four of the past five meetings between the two sides, which includes a 26-point victory when they last met in Round 17 last year.

Bews, Cooper Stephens, Esava Ratugolea and Shannon Neale are the emergencies.

Geelong will announce its medical substitute an hour prior to the first bounce.
