The Bulldogs could be without captain Easton Wood for the remainder of the 2018 season, after scans confirmed the skipper would miss the next 10-12 games with a high-grade hamstring injury.
Wood suffered the injury during the second quarter of the Dogs' loss to Port Adelaide on Thursday night, in a game that may have been his last of 2018.
Dogs midfielder and Brownlow Medal fancy Jack Macrae also suffered a hamstring injury, although his injury has been confirmed as a low-grade strain.
Macrae will be sidelined for up to a month.
Lukas Webb suffered a fractured thumb against the Power, and will also miss the next 3-4 weeks.
Tom Boyd (dislocated finger), Marcus Bontempelli (knee) and Toby McLean (shoulder) will all need to pass fitness tests in order to face North Melbourne next Saturday.
