UFC heavyweight Francis Ngannou proved once again that he’s a bad, bad man.  He finished Jairzinho Rozenstruik just seconds into the first-round at UFC 249 on Saturday night.

The early finish was Ngannou’s fourth straight.  As you can see in the replay of the fight, Rozenstruik’s chin was absolutely no match for Ngannou’s heavy hands.
