Luke Cleary, Zac Walker, Tim English and Luke Kennedy all remain in concussion protocols heading into Saturday night's clash with Collingwood at Marvel Stadium.

“Cleary received some high contact in the second quarter of the game against Melbourne and as a result had some concussion-related symptoms,” Bulldogs Head of Sports Medicine Chris Bell said.

“He was immediately removed from the game. Luke will work with our doctors to progress along the concussion management pathway to determine his return-to-play plan.

“Zac Walker, Luke Kennedy and Tim English have continued to progress within the concussion protocols. All players still have some boxes to tick, including performing within a main training session before a return-to-play plan will be confirmed.”

Cody Weightman is nearing a return to football but will be tested this week before determining his availability.
