Argentina No. 8 Pablo Matera was in no mood for sporting formalities, after his side's 53-3 pasting by the All Blacks at Hamilton on Saturday.
Walking in line and shaking hands with his NZ opponents in the traditional post-match manner, Matera overlooked All Blacks hooker Dane Coles, shunning the veteran's hand and offering him nothing but a shove and a look of disdain.
Coles brushed it off and moved on to the next player, while Matera did the same.
In the dying stages of the match, Matera reacted strongly to some words that appeared to come from replacement Coles - a reputed on-field trash talker - as a scuffle broke out between the two teams.
"Didn’t shake Colesy’s hand? He wouldn’t be the first player," quipped All Blacks coach Ian Foster after the game.
"Everyone loves Colesy."
The All Blacks then rubbed further salt in the Pumas' wounds with their seventh and final try on a miserable evening for the visitors.
The win propelled the All Blacks to the top of the Rugby Championship standings, where they'll remain after the Wallabies were soundly beaten by the Springboks at Sydney.
