Western Bulldogs defender Easton Wood will miss up to three weeks with a hamstring injury, while speedy forward Laitham Vandermeer faces a race against time to return this year.
Wood and Vandermeer both injured their hamstrings in the first half of last week's 11-point loss to Geelong.
Vandermeer is set to miss around six weeks, meaning he won't return unless the Bulldogs go deep into the finals.
Wood will miss Sunday's clash with West Coast and next week's match against Hawthorn, but he could return for the final round contest against Fremantle.
"At the end of the second quarter, Easton came off and reported some low-level hamstring tightness," medical services manager Chris Bell said.
"We removed him from the game because we didn't want to take any risk and scans have since confirmed that he does have a low grade hamstring injury."
The Bulldogs (7-7) sit in 10th spot, and might have to win their remaining three games in order to make the finals.
