Panthers, Patriots Brawl At Joint Practice, Fan Injured In Melee

The Patriots and Panthers' joint practice Wednesday looked more like a WWE match ... 'cause the two teams got into a huge brawl -- and the skirmish was so big, a fan was actually injured in the melee.

The fight initially started after Carolina star running back Christian McCaffrey was pissed over a tackle Patriots defensive end Deatrich Wise Jr. put on him during 11-on-11 drills.

The 26-year-old got up after the hit and threw the ball at the Pats D-lineman ... and that's when all hell broke loose.

Video shows a bunch of Panthers players going after Wise and his teammates right near fans who were sitting in the bleachers -- and, at one point, players were thrown into the spectators.

According to Pat's reporter Tom Curran, a woman sitting in the stands was injured after one of the players' helmets hit her foot.

She reportedly refused any medical help, and did get an offer for tickets to a game later this season.

This is the second brawl between the Panthers and Pats this week -- on Tuesday, several players, including Pats' Kendrick Bourne, Kristian Wilkerson, and Panthers' Kenny Robinson, went at it.
