I doubt this brawl went any further than what we already saw. The other guys were rushing in the room to break it up before the two even hit the bed. It'll be separated quickly.
I didn't check the site to see if they're fighting each other, but I hope they are. J-Rock was supposed to be a top prospect, and War Machine seemed like he could hang in there. Based on Hughes' talk of Rollins ground game, he'd probably win the fight by submission.
