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 onย SEN,ย Buckley condemned the behaviour directed at Selwood from Magpies fans.

โ€œUnacceptable, donโ€™t like it, donโ€™t like it at all,โ€ he said of the boos during Saturday night's match.

โ€œI 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.

โ€œI 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.

โ€œThat doesnโ€™t mean that I donโ€™t understand it, but I just donโ€™t like it.โ€

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.
