Former Collingwood coach Nathan Buckley has labelled the booing of Cats captain Joel Selwood as "unacceptable".

Selwood, who broke the record for games captained during the Round 2 win over Collingwood, was met with boos from the MCG crowd throughout the evening following an incident involving young Magpie Jack Ginnivan.

Almost each time the three-time premiership Cat gained possession in the match, a vocal variety from the 52,974 crowd hammered taunts toward Selwood on a night where Geelong celebrated their skipper's record-breaking feat.

The Cats would come away with the last laugh as they overcame a 37-point deficit to snatch their second win of the season, while simultaneously handing Collingwood their first defeat of 2022.

Selwood was given a guard of honour off the field after the 13-point win, but the scenes leading up to the final siren marred moments of the spectacle.

Speaking on SEN, Buckley condemned the behaviour directed at Selwood from Magpies fans.

“Unacceptable, don’t like it, don’t like it at all,” he said of the boos during Saturday night's match.

“I understand the emotions that come with following your team and witnessing a great contest before your eyes and there is a cathartic effect of going to the footy where we release those emotions - anger, stress and we get emotionally involved.

“I think cheer as loud as you want, hoot and holler as loud as you like, but I just think booing or denigrating someone is just not something that needs to happen.

“That doesn’t mean that I don’t understand it, but I just don’t like it.”

Buckley famously slammed Essendon fans during the post-match medal ceremony of the 2019 ANZAC Day clash as Scott Pendlebury was awarded best-afield honours.

After a game highlighted by contentious umpiring decisions, Pendlebury was met with jeers as he was awarded the ANZAC Day Medal, with Buckley stating to the crowd: "Shame on anyone that booed a champion."

Selwood surpassed Carlton great Stephen Kernahan's all-time record for games captained, with the weekend seeing the Cats veteran play his 227th match with the proverbial captain's armband.

Round 4 will see Geelong face Brisbane at Kardinia Park on Friday night, while Collingwood will host West Coast at Marvel Stadium the following afternoon.
