Hawthorn coach Sam Mitchell lost his temper in a moment of madness during the Hawks’ disappointing loss to Brisbane on Saturday afternoon.

The Hawks were comprehensively outplayed by the reigning premiers at the MCG, losing by 33 points.

There was a moment late in the third quarter that proved too much for Mitchell.

Hawthorn were trailing by 21 points when Josh Weddle nearly pulled off a team-lifting play. The emerging star took a great mark on the wing and immediately took off despite having a Brisbane player on his hammer.

Weddle showed off his athletic prowess with three bounces, but let himself down with a poor kick inside 50 that was neither a shot at a goal nor a pass.

Brisbane defender Jack Payne was able to take a comfortable mark in the goalsquare to keep the Hawks at bay.

It was the second time in as many minutes, Payne had taken an interception mark from a poor kick inside 50.

The play left Mitchell furious. As cameras panned up to the coach, Mitchell smashed the advertising board behind him, breaking it in the process.

Mitchell and Weddle could be seen chatting at the three-quarter time break with the Hawthorn coach all smiles this time.

But the smile was quickly wiped off his face 30 seconds into the final quarter when Cam Rayner kicked a goal to put the Lions up by 27 and ruin any chances of a Hawthorn comeback.

The victory lifts Brisbane to the top of the ladder, although Collingwood could reclaim top spot later on Saturday.

Hawthorn meanwhile could drop as low as sixth after suffering their fourth loss of the season.

It was the Lions’ first win over Hawthorn since 2019, having lost every game across the past five years even though they had been strong favourites.

It was fitting in Sir Doug Nicholls Round that Callum Ah Chee should star and Charlie Cameron awoke from his season-long slumber.

Ah Chee was the best forward on the ground, kicking four goals and limiting the influence of Hawthorn captain James Sicily as an intercepting defender.

After entering the match with 8.15 this year, Cameron set the MCG alight with three goals in three minutes late in the second quarter.

Scores were level until Cameron put through his first at the 22-minute mark, slotting two more goals in quick succession, which included a dance celebration for his second.

A Levi Ashcroft major gave the Lions a 23-point halftime lead they would never relinquish.

Hawthorn had patches in the third quarter when they threatened to get back in the game, but the Lions sealed the match with the first three goals of the final term.

Once a bogey venue for Brisbane, the Lions have now won five of their past six games at the MCG, including last year’s preliminary and grand finals.

It was the first time the Lions have beaten Hawthorn at the MCG since 2004.

Hawthorn were badly beaten in the midfield, as Lachie Neale and Will Ashcroft combined superbly, as they did on grand final day last year.

Livewire forward Connor Macdonald was clearly the Hawks’ most influential player, booting three first-half goals.

Brisbane will head home and have just five days before they host Essendon at the Gabba on Thursday night.

The Hawks face another huge test on Friday night when they face premiership favourites Collingwood at the MCG.
