Hawthorn have made a late change ahead of their clash with the Western Bulldogs at Etihad Stadium on Saturday night.

Conor Glass has been withdrawn, and will be replaced in the side by Jonathan O'Rourke.

โ€œWeโ€™ve got guys knocking down the door at Box Hill, so weโ€™d rather not take the risk if he isnโ€™t 100 per cent,โ€ Hawthorn's GM-Football Graham Wright told hawthornfc.com.au.

โ€œJono has been a strong performer in the VFL for some time now, so weโ€™re excited to see him grab his opportunity tonight."

The Dogs will enter the clash as named.

O'Rourke hasn't played an AFL game since round 20, 2016.
