Western Bulldogs midfielder Tom Liberatore will be sidelined for at least the next fortnight with a hamstring injury.

Liberatore was able to play out the win over Adelaide, with scans later confirming the extent of the injury.

“During the weekend’s game, Tom developed some low-level hamstring tightness,” Bulldogs Head of Sports Medicine Chris Bell said.

“Scans have since confirmed a low-grade hamstring injury.

“Tom won't play in the Round 4 game against the Bombers, and we will work to confirm return to play plan across the next period of time.”

Laith Vandermeer remains a test following his concussion, while Zac Walker is 5-7 weeks away.
