MILLWALL fans were involved in an away end brawl during Saturday's Championship clash with Cardiff.
Stewards and police were seen among the supporters during the scuffles in the Welsh capital, which occurred during the Lions' 3-1 defeat in the Championship fixture.
It is unclear what began the incident, or whether any arrests were made.
A section of Millwall fans had earlier booed the taking of the knee before the match.
Cardiff players took part in the anti-racism gesture while their opposition remained standing, with the home crowd applauding the stance.
Lions boss Gary Rowett made headlines during the week by blaming those taking the knee for 'causing a rift' - earning a sharp rebuttal from ex-Championship winning captain Jobi McAnuff.
On the pitch on Saturday, Cardiff took all three points after a four-goal second-half.
A quiet start gave way to Aden Flint's header on 66 minutes.
