Everyone LOVES a good knockout and this weekend was great for those. There was a huge upset in the world of boxing Elieder Alvarez knocked out Sergey Kovalev after being a 4 to 1 underdog. TJ Dillashaw ended any talk of his 1st fight with Cody Garbrandt being a fluke by knocking out his former teammate in the 1st round. Both of those might have been trumped though by a bouncer landing what possibly could've been the cleanest uppercut of all time. Check them all out below and decide which one was the best.
