GEELONG has made one late change ahead of its blockbuster showdown with the Western Bulldogs at Skilled Stadium.

Speedster David Wojcinski has been left out of the side with a sore achilles, with 20-year-old Ryan Gamble the last minute inclusion.

Gamble has played eight senior games, with seven coming this season after his 2006 debut.

The Cats will start with Gamble, Mark Blake, Brent Prismall and James Kelly on the bench.

The Bulldogs will go into the match as selected, with Nathan Eagleton, Daniel Giansiracusa, Stephen Tiller and Jarrod Harbrow beginning on the pine.

Conditions are currently dry in Geelong with a very light showers forecast for late in the afternoon, and a top of 14 degrees.
