Brisbane Lions defender Harris Andrews will see specialists this week to map out his course of recovery, following a sickening blow from Jeremy Cameron in round 14's clash against GWS.

A worsening condition required the Lions defender to brave 24 hours in hospital, with bleeding on the brain and a critical concussion; Giant Jeremy Cameron was swiftly suspended, for five matches.

"He'll (Andrews) see a neurosurgeon this week and he'll have another set of concussion tests," coach Chris Fagan told SEN on Monday morning.

"He did some more of those concussion tests last week and there's been a definite improvement, but he's still not good enough to play."

Andrews' head knock came in the first quarter of Brisbane's loss to GWS at the Gabba, clashing with Cameron in pursuit of a mark and later carted away on a stretcher.

Given Andrews' serious condition, Fagan said he is reluctant to send the player to the field without proper precaution first.

"I doubt very much he'll be available for this weekend, but fingers crossed he might be available for the following weekend," Fagan said.

"He won't play until he ticks all the boxes."
