AFL's Eagles still sweating on Yeo fitness

West Coast coach Adam Simpson says he'll wait until after training on Thursday night before making a call on the availability of midfielder Elliot Yeo.

Yeo missed last week's win over Gold Coast with a quad injury, and he's no certainty to return for Sunday's AFL clash with the Bulldogs at Etihad Stadium.

Andrew Gaff is set to return from concussion, with the Eagles aiming to snare their fourth win on the trot.
