Danny Rose apologised for setting a bad example after frustrations boiled over during Tottenham's bad-tempered 2-2 draw with Chelsea on Monday night.
Tottenham and Chelsea may yet face retrospective action from the English Football Association, with Mousa Dembele particularly likely to receive a rebuke after he appeared to claw his fingers down Diego Costa's face during a skirmish at the end of the first half.
There were several other incidents of petulance during the game and matters came to a head again at full-time when a melee in the tunnel resulted in Chelsea's interim manager Guus Hiddink being pushed to the ground.
Rose, who sparked the first brawl after clashing with Willian and was booked, said he was sorry for how the game may have looked to young viewers.
"It is not nice to see for kids here or kids watching on TV. I apologise if it looked bad on TV," Rose said. "It is a London derby. It is to be expected. We wanted to win and they wanted to stop us having any more say in the title race."
