MANILA, Philippines - One thing that makes boxing different from all other sports is, you never know when a fight is going to end. In basketball, a second quarter jumper from Kobe Bryant can't end a game but a second round uppercut from Miguel Cotto can end a fight.

The year 2015 had its share of big knockouts, and this (wonderfully edited) compilation of stoppages from around the world compiled by Gorilla Productions will attest to why the sport is called the hurt business.

The only Filipino who made the list was Ernie Sanchez at number 20, and not on the side he would've wanted to be. He was knocked out in 3 rounds by Oscar Valdez on December 12.

There is certain to be some names on this video that are new, and some selections that you may not agree with. Let us know in the comments section below which knockout you felt was the best. – Rappler.com
