England’s defeat by South Africa was marred by a post-match confrontation between players Mike Brown and Joe Marler and fans.
The Harlequins duo exchanged angry words with supporters after England lost their fifth straight Test, beaten 23-12 by South Africa in Bloemfontein.
England head coach Eddie Jones said he did not see the incident.
But asked if his players won or lost with dignity, he told BBC Radio 5 live: “I think they always do.”
England led 12-0 but the defeat means South Africa have wrapped up the series 2-0 with one match to play.
A further sign of England’s frustration came when scrum-half Ben Youngs walked away from a television interview after one question.
He subsequently apologised on social media for conduct that was strongly criticised by Sir Clive Woodward in his role as a pundit.
“Just wanted to say sorry I walked off during my interview with Sky Sports,” Youngs said on Twitter.
“Obviously was very emotional and disappointed with result. We go again in Cape Town.”
