Geelong will be without Lawson Humphries for next week's clash against GWS after entering concussion protocols.

Humphries featured in Saturday night's win over Collingwood, but following a post-match head assessment, failed the test and will miss at least the next 12 days.

The Cats defender was checked during the second term when he came to the bench and passed the assessment, but suffered a delayed concussion.

Humphries gathered 13 disposals and three marks in the victory.

He will join ruckman Rhys Stanley on the sidelines, who was subbed out of the contest with a hamstring injury at quarter-time.

Geelong coach Chris Scott was unable to provide any meaningful update on Stanley's injury, but has already contemplated how they'll look to cover for him.

"We can guess and give you a number, and it won't be right," Scott said.

"Anyone that tells you what hamstring injuries are in the moment, they're just lying to you."

"(Blicavs) was critical. When we lost Stanley to a hamstring... I won't lie to you, I thought, โ€˜Okay, this is going to be a real challenge now', and we're going to need some guys to step up and play some big minutes."

Geelong are hopeful that defenders Jack Henry and Jake Kolodjashnij will return to the senior side.
