Anderson Silva had already cemented his UFC legacy ahead of his UFC Fight Night main event with Uriah Hall, but the former middleweight champion was trying to make one final statement in his final trip to the Octagon. The fairy tale ending wasn't to be, however, with Hall scoring a fourth-round knockout in Las Vegas' UFC Apex facility. At just 25, Davis (24-0, 23 KOs) created a viral highlight that's sure to gain acceptance as boxing's best knockout of 2020 as he cornered Leo Santa Cruz (37-2-1, 19 KOs) in Round 6 and ended a close fight with a flush left uppercut to the chin that removed the four-division champion from his senses.
