While things might not have got feisty on the field on Sunday they definitely got feisty and fired up off the field.
A wild brawl broke out between Bears' fans and Rams' fans.
Punches were thrown left and right and it was all caught on video.
Eventually TMZ got their hands on the video.
People were forced to switch chairs during the game because it got so intense and things got worse when fans met up outside as well.
