Brisbane defender Darcy Gardiner is sure to come under scrutiny from the Match Review Officer following a late bump on Collingwood's Josh Daicos during Thursday night's encounter between the Lions and Magpies.

During the opening term of Brisbane's seven-point victory at the Gabba, Gardiner arrived late to a near-uncontested mark for Daicos, electing to bump from behind and hammer the young Magpie into the turf.

Gardiner was immediately placed on report for rough conduct, with Daicos awarded a 50m penalty and a subsequent shot from the goal square after getting back to his feet.

While Daicos was able to play out the rest of the match, Gardiner will face a nervous wait throughout Friday as the MRO weighs up their verdict on the bump.

Likely to be graded low impact and body contact, Gardiner is likely to avoid a suspension despite the conduct potentially being assessed as intentional.

Collingwood tall Mason Cox could also receive some attention from the MRO for his collision with Lion Brandon Starcevich during the second quarter of the game.

Cox leaped knee-first into a marking contest where Starcevich was placed under the ball, with the Magpies forward arriving late and have a timely impact on the ball.

Starcevich was left grimacing on the ground after receiving a knee in his back, however was able to play out the match.


"I wouldn't say that's in the marking contest," commentator Luke Hodge said.

"He had leapt (off the ground)."

Cox wasn't the only key-position Magpie to spark some concern for senior coach Craig McRae during the Round 5 loss, with forward/ruck Darcy Cameron substituted out of the match with a rib injury.

Cameron was replaced by medical sub John Noble at three-quarter time, having his evening ended after recording seven disposals, three marks and a goal.

Collingwood will await to see the significance of the setback but will hope an 11-day turnaround has Cameron available for their clash with Essendon on ANZAC Day.

The defeat sees Collingwood fall to a 2-3 record for the season, while the Lions claimed their fourth win to remain second on the ladder.

Brisbane will face Queensland rivals Gold Coast at Metricon Stadium next Sunday.
