The Western Bulldogs are once again fielding an unchanged line-up for their do-or-die semi-final against Brisbane at the Gabba on Saturday night.

Ryan Gardner and Josh Schache have both retained their spots in the side, after being late inclusions in the Bulldogs’ 49-point elimination final win over Essendon at UTAS Stadium.

Mitch Wallis, Zaine Cordy, Anthony Scott, and last week’s unused medical substitute Jason Johannisen have been named as emergencies.

One of the four will be confirmed as the medical substitute an hour before the bounce on Saturday night.

The game will be broadcast live on Channel 7 and Fox Footy, with the winner to advance to a preliminary final against Port Adelaide.

The Bulldogs have spent the week in Launceston, and are due to fly out to Brisbane on Friday morning.
