Geelong star Jimmy Bartel heads three key Cats in doubt for next Sunday's home AFL clash with Adelaide because of injury.

Bartel suffered concussion in Saturday night's hard-fought win over St Kilda, while fellow midfielder James Kelly hurt his ankle and veteran defender Darren Milburn had an Achilles tendon problem.

Mitch Duncan suffered a knock to his head when tackled by Justin Koschitzke, but the Cats were not so concerned about his availability.

"They are definitely no certainties of playing," Geelong football manager Neil Balme said of Bartel, Kelly and Milburn.

"We will see how they go through the week."

Saints' defender Jason Blake (knee) was supposed to return against the Cats, but he was a late withdrawal.

Young Essendon star Michael Hurley suffered calf tightness in Saturday's loss to North Melbourne.

Hurley was one of the Bombers' best players with four goals as they suffered their fourth straight loss.

Coach James Hird is confident Hurley will be fit for Friday night's clash with Hawthorn.

Hawthorn's injury woes continued on Saturday as they easily dispatched Gold Coast in Launceston.

Ryan Schoenmakers had to pull out of the team after suffering a foot injury at Thursday training.

That meant the Hawks made five changes for the match, all due to injury.

They also subbed out Rick Ladson during the match with a thigh strain.

Brisbane key position player Mitch Clark had an ice pack on his ankle after Saturday night's loss to Richmond at the 'Gabba.

Clark was subbed out of the game at halftime, while teammate Todd Banfield also hurt his hamstring during the final term.

Brian Lake's rotten luck continued on Saturday when he suffered an eye injury while playing in the VFL.

The Western Bulldogs' All-Australian key defender has struggled for form throughout this season.

Lake had to go to hospital, but was released later in the day, with the Bulldogs unsure about the severity of the injury.
