Tempers flare during preseason training camp; it’s hot, you’re outside all day running drills…and it’s hot.

On Sunday while running full-contact reps, Tyler Patmon jammed Dez Bryant up off of the line, so hard that it took his helmet off. So Bryant pulled Patmon’s helmet off, and Patmon got the first jab in. A couple more punches flew before their teammates stepped in to split them up.

This isn’t out of the ordinary by any means, but normally the only evidence we’d have of it happening is a grainy video from an NFL beat writer shot vertically on their cell phone. But this time the Cowboys tweeted a link to the full video– GIF included– from their official account. 

Gotta love sports in 2015.
