Western Bulldogs defender Alex Keath will be sidelined for an extended period after suffering a hamstring injury in the AFL match against Brisbane.

The incident occurred in the final moments of the clash at Marvel Stadium.

“Late in the fourth quarter, Alex sprinted into a contest and over-stretched trying to execute a spoil,” Chris Bell, Head of Sports Medicine at the Bulldogs, said.

“This mechanism has caused a moderate grade hamstring injury. We expect Alex to miss the next 5-7 weeks.”

Duo Luke Cleary and Jordan Croft have entered concussion protocols after separate incidents in the VFL.

“From our VFL game on the weekend, unfortunately we had two players who suffered concussions – both Luke and Jordan have entered our concussion management framework,” Bell said.

“Both will miss the game this week which leads us into the bye round.

“We will work with both players across the next two weeks to determine their availability coming into the Round 16 AFL match.”

In more positive news, Ed Richards and Cody Weightman will both be tested at training this week.

“Ed didn’t quite tick every box that we needed him to within our return to play protocol following his concussion,” Bell said.

“Ed will look to fully train tomorrow, with us optimistic that he will be in line to return to availability this week.

“Cody has been the ultimate professional in his rehabilitation following his elbow reconstruction. He has been dedicated and left no stone unturned to accelerate his recovery following his elbow surgery.

“His surgeon couldn’t be happier with his progress and last week has cleared him to return to full contact.

“We will work through a process with Cody across this week to confirm his availability.”
