Juventus lost 3-0 at home to Lazio in Serie A on Sunday, and several Juventus supporters were filmed fighting each other in the stands during the match, causing a brief stoppage in the first half.
Referee Davide Massa blew his whistle to stop play while the situation was sorted out.
Stoppage during the first half
Stadium stewards intervened and the interruption lasted only a few minutes before the referee authorised the match to resume.
The supporters involved in the altercation were escorted out of the Allianz Stadium by stewards, and paramedics were present to provide medical assistance to those injured during the incident.
Players appealed to supporters
Douglas Luiz approached the Juventus fans and yelled at them in a plea to stop. Weston McKennie was also seen gesturing to the supporters on the touchline.
Reaction at full-time
Many fans left the stadium before the full-time whistle, and lots stayed behind to boo the players as they approached the stands after full-time.
Video footage emerged on social media of one supporter burning his scarf as the players applauded the supporters after full-time.
