HARRIS Andrews has suffered bleeding on the brain following his sickening incident with GWS forward Jeremy Cameron on Saturday night, and is set to miss at least two matches.
After his condition worsened post-match, the Brisbane vice-captain was admitted to hospital and underwent a series of tests.
He was released on Sunday night and is staying at his parents' house.
BRUTAL HIT Andrews out cold
The Lions said in a statement on Monday morning that Andrews had suffered a severe concussion and "an associated small bleed on the brain".
It said the club had been in constant consultation with a neurosurgeon, who would assess Andrews again in two weeks' time.
"Our discussions with the neurosurgeon have been encouraging as they expect Harris to make a full recovery," football manager David Noble said.
"He will have a follow-up scan in two weeks' time, when we will know more."
HOW MANY FOR JEZZA? Tribunal date looms
Andrews was sent crashing to the Gabba turf in the opening quarter of Saturday night's match after Cameron appeared to catch him with an elbow in a marking contest.
The Giants forward was reported for the incident.
Andrews was taken from the ground on a stretcher and watched the second half from the bench.
