Tim O’Brien will make his debut in the red, white and blue this weekend after being named to play against Richmond on Saturday night. 

The 27-year-old joined the Club over the off-season as an unrestricted free agent, having played 97 games and kicking 73 goals for Hawthorn across nine seasons.

O’Brien impressed during pre-season but had a delayed start to his Bulldogs’ career after suffering a hamstring injury on the eve of the campaign. 

The utility will play in the backline for the Bulldogs, replacing key defender Alex Keath. 

The defender will miss at least the next three weeks of football after sustaining a hamstring injury at training during the week.

Louis Butler has been included on the interchange after strong VFL form, collecting 27 disposals and a goal in the victory over Northern Bullants. 

Bailey Williams returns to the backline in place of Zaine Cordy, who will miss the round four clash after entering concussion protocols.

Mitch Wallis, Buku Khamis, Jordon Sweet and Lachlan McNeil have been named as emergencies. 

The medical substitute will be named from among the emergency list before the first bounce.

The game against the Tigers at the MCG will get underway at 7:25pm local time. 

The fixture will be live on Channel 7 and Fox Footy.
