The 64-year-old concert-goer was injured with a broken leg and a concussion outside the stadium after getting into a dispute with a woman.
Thirty-eight-year-old Reece Hopkin and 42-year-old Chad Reeves are each charged with one felony count of battery with serious bodily injury.
The viral video of the attack captures its end, with the person recording the video following the alleged attackers through the parking lot. Hopkin is accused of grabbing the man's phone and throwing it on the ground.
