The UFC’s annual stop in London went down Saturday with UFC Fight Night 255 at The O2, a card which saw eight of 13 bouts go to the scorecards.

One fight that didn’t reach the scorecards, however, was the main event. That’s where Sean Brady (18-1 MMA, 8-1 UFC) delivered the most emphatic performance of his career when he submitted former welterweight Leon Edwards (22-5 MMA, 14-4 UFC) in the fourth round to place his name in title contention.
