Stipe Miocic, Junior dos Santos engage in flex off contest during NBA game

Stipe Miocic and Junior dos Santos will collide for the second time at UFC 211, scheduled for May 13 at the American Airlines Center in Dallas, Texas, but already “battled" in the arena on Thursday night.

The current and former heavyweight champions were in attendance for the Mavericks vs. Clippers game, and engaged in a flex off contest.

Miocic (16-2), who went 3-0 in 2016 with first-round knockout victories over Andrei Arlovski, Fabricio Werdum and Alistair Overeem, is looking to avenge his last loss inside the Octagon, when he was beat by “Cigano" (18-4) by unanimous decision in 2014.
