— -- Minutes after Michael Bisping knocked out middleweight champ Luke Rockhold with a flurry of punches in the first round of UFC 199's main event, a slew of social reaction filtered in.

The reaction of the night might have come from Chris Weidman, whose spot Bisping filled when Weidman pulled out on May 18 with a neck injury.
