GEELONG has been forced into making a late change ahead of its Round 22 clash with St Kilda at GMHBA Stadium on Saturday.

Defender Tom Stewart is a late withdrawal after injuring his foot at training on Thursday.

"Tommy Stewart sustained a foot injury in a marking contest at Thursday's training," GM of Football Simon Lloyd says.

"He's not available this week and we'll consult relevant specialists over the coming week."
