New Orleans Saints and Atlanta Falcons fans have a nasty history, which was heightened a bit on Sunday.

The action on the field paled in comparison to what was going on in the stands inside Mercedes-Benz Stadium.

In the cheap seats, fans from both teams took verbal arguments in the cheap seats and made them dangerous by throwing punches.

The first video showed what looked like a Falcons fan knocking a Saints fan to the ground. Instead of letting it go, the fan decided to stomp on his head several times, to the point that it appeared he knocked the guy out.

In a second video, also in the cheap seats, the fans can be seen falling down seats as they brawl with one another.

There was, in fact, a game going on during this day amid all of the fighting.

The Atlanta Falcons didn’t score an offensive touchdown in Week 4, yet they handed the New Orleans Saints their second straight loss.

Younghoe Koo kicked a 58-yard field goal with two seconds remaining as the Falcons rallied for a 26-24 victory over the New Orleans Saints.

Koo was the MVP as he connected from 53, 44, and 42 yards to give the Falcons a 2-2 record.

The Falcons had previously lost their first two games at Mercedes-Benz Stadium but luckily made the home fans happy with their third chance against the hated New Orleans Saints.

Kirk Cousins threw for 238 yards on 21-of-35 passing with one interception, with Drake London leading the team with 64 yards receiving on six receptions.

Both teams are 2-2 as they head into Week Five, where Atlanta will take on the Tampa Bay Bucs, and New Orleans will face off against the Kansas City Chiefs.
