Saul “Canelo” Alvarez and Gennady “GGG” Golovkin collide for the unified WBA (Super), WBC, IBF, The Ring magazine, and lineal middleweight championship of the world this Sat. night (Sept. 16, 2017) at T-Mobile Arena in Las Vegas, Nevada, live by way of HBO pay-per-view (PPV).

Before that happens, both pugilists must take the stage in “Sin City” for the official Canelo vs. Golovkin weigh ins, which begin promptly at 3:30 p.m. ET in the embedded video player above.

Boxing is all the rage these days, particularly in the mixed martial arts (MMA) circles, thanks to Conor McGregor’s gritty performance against Floyd Mayweather Jr. last month in Las Vegas (see it).

But this one is for the purists.
