The Western Bulldogs will be without defensive duo Alex Keath and Ed Richards for this week’s clash with the Adelaide Crows.
Keath has been a significant contributor for the Bulldogs this season, playing every game.
However, the 29-year-old was subbed out of Saturday night’s win against Melbourne and will now miss up to a month of football.
“In the first quarter, Alex came to the bench with a hamstring injury,” head of sports medicine, Chris Bell, said.
“Although low grade, I expect Alex to miss the next three to four games of footy.”
Richards will be unavailable this week after being concussed in the third quarter.
The 22-year-old has played four games in an interrupted season, after missing the first three months due to an ankle injury.
“Ed was involved in a contest where he clashed heads. This caused him to have some concussion symptoms,” Bell said.
“Ed has come in well today and we’ll work through a process in the next 10 days or so to determine his availability.”
The timeline has become clearer for experienced ruckman Stefan Martin, who continues to work his way back from a groin and hip issue.
Martin is on track to return to availability in the next 3-4 weeks.
