Hawthorn star Tom Mitchell's Brownlow Medal hopes hang in the balance on a busy day for AFL match review officer Michael Christian.
Mitchell's high elbow to North Melbourne ruckman Todd Goldstein and Lindsay Thomas' jarring bump on Scott Selwood in his first game for Port Adelaide were key talking points from round five.
Christian will review the first seven games of the Anzac round on Monday, with his assessment of Mitchell's ill-advised elbow much-anticipated.
The prolific Hawks onballer, one of the favourites for the Brownlow after four rounds, gave away a free kick that cost a goal after he thrust his right elbow at Goldstein's head in an off-the-ball incident in the second quarter of the Roos' upset win.
But he received a boost in the aftermath, with Goldstein doing his best to uphold the players' code.
"He only just got me so it was probably a bit lucky," Goldstein told the Seven Network.
"They seemed to be targeting me and trying to get a hit on me but he just slipped high.
"It's a pretty good effort by him too. It's hard to get me high.
"It wasn't hard, I barely even noticed, it was like a fly touching me really.
"He'll be fine."
In an eventful match, young Hawk Ryan Burton will also come under scrutiny after he was involved in a collision that knocked out new dad Shaun Higgins.
The North veteran's wife gave birth to their first child just hours before he took the field. He was reported to be lucid and talking as he was transported to Epworth Hospital.
The Kangaroos' Cameron Zurhaar was reported for bundling Hawthorn's David Mirra into the Etihad Stadium fence.
Thomas faces suspension after he was reported for rough conduct over a heavy and high hit on Selwood during the Power's 34-point loss to the Cats at Adelaide Oval on Saturday night.
Geelong premiership skipper Cameron Ling launched a blistering attack on Thomas, labelling the Power forward's hit on "a dog act".
Selwood was knocked out of the game with a concussion following the ugly second-quarter incident.
"Lindsay Thomas' act was nowhere near courageous - it was cheap," Ling said on 3AW radio on Sunday.
"That one, for me, is as outlawed and as cheap a shot as you can take on a footy field ... that was a dog act."
Under new guidelines this season, Thomas will receive a two-week ban if the incident is classified as careless conduct with high impact to the head.
He could be sent straight to the AFL Tribunal if Christian deems it intentional conduct.
Power coach Ken Hinkley said the collision was "ferocious" but unintentional.
Greater Western Sydney ruckman Dawson Simpson will come under review for the first-quarter collision that put St Kilda's Jack Newnes out of their drawn game with concussion.
