Kettering Town players Moses Ashikodi and Jean-Paul Marna were both sent-off for fighting each other on the pitch during their 5-3 Blue Square Premier defeat to Hayes & Yeading.
Kettering were awarded a penalty in the last minute of the match at their home ground of Nene Park while trailing 5-2, and both Ashikodi and Marna argued over who should take it.
Ashikodi eventually took the spot kick but it was saved by Hayes keeper Delroy Preddie and then from the resulting corner Marna scored.
As the players returned to the centre-circle. the two forwards restarted their argument and the whole incident eventually led to blows with the referee Rober Whitton then sending both players off.
Kettering's manager, chairman and players all refused interview requests at the end of the match but fans took to popular Kettering fans forum 'Poppynet' to register their disgust at the incident.
One user called 'fan 4 a year' said: "If me or you were to do that at work today you WOULD be sacked no discussion. What shocking role models to all the kids who idolise them."
"Just up, and it all feels like a bad dream. What the he'll were they thinking of last night?" added fan 'Geddingtonpoppy'.
"I still think both should go, and we've got to build up from what seems like rock bottom. Surely the season can't get any worse than this? (Well except relegation of course)"
Some fans were willing to sympathise with Marna - who has played 200-odd games for the club since signing in 2006 - but not everyone was so forgiving of the Senegalese striker just because of his past.
"It doesn't matter what he's done for the club or how much he loves the club or how good or how entertaining he is," said NickM.
"What happened was completely inexcusable and JP must be equally held to account for it. Whatever sanction is applied to Ashikodi MUST be applied equally to JP. For me neither of them should ever play for the club again."
Kettering are currently struggling in the Blue Square Premier League in 20th position - just one place above the relegation zone.
