Video from MetLife Stadium, posted to social media, shows a Cowboys fan throwing some serious haymakers at a Giants fan during the “Thursday Night Football” matchup.
It’s unclear what started the brouhaha, which came during the first quarter, after Big Blue kicker Greg Joseph put the Giants up 3-0 with a 52-yard field goal.
Fans seated nearby seemingly attempted to intervene, they weren’t able to stop the Cowboys fan, clad in a vintage Troy Aikman jersey, from raining down some brutal blows.
The Giants fan appeared dazed, needing some help to stay upright from another Big Blue supporter.
