Boxing fans in attendance at Vergil Ortiz vs Serhii Bohachuk on Saturday night were treated to fantastic action, and some even experienced it first hand.
Prior to the main event, a video went viral showing two fans fighting in the stands.
In the clip, the pair went at it for roughly five seconds while others in attendance cheered.
It all became very serious very quickly though as one of the men landed a huge right hand on the other, knocking him out cold.
Boxing reporter Steve Kim tweeted from ringside: “Whoa!! Fight breaks out and some dude gets absolutely clocked with a right hand.
