For the third consecutive UFC event, the headlining bout attracted the bulk of the post-fight attention due to a spectacular knockout. This time it was Alexander Gustafsson  (16-2 MMA, 8-2 UFC) who delivered the goods when he stopped Jimi Manuwa  (14-1 MMA, 3-1 UFC) with a brutal assault of strikes in the second round of Saturday’s UFC Fight Night 37 headliner. The organization’s 15th English event was a good one, with five of the nine UFC Fight Pass-streamed matchups ending with a knockout or submission, four of which occurred in the first round. UFC Fight Night 37, which took place at London’s O2 Arena, was the second of four UFC fight cards slated for a busy month of March. With much more MMA still ahead in the coming weeks, take a minute to look back at 25 post-event facts to come out of the UFC’s most recent international show.
