The Golovkin vs Martirosyan fight hasn't even begun yet and there has already been a ton of drama in the run up to the bout. And you can live stream the whole thing from the comfort of your favorite device.
Gennady Golovkin was set to have a big money rematch with Mexican boxer Saul Alvarez, but the latter failed a drug test and was banned from competing so the late replacement of Vanes 'Nightmare' Martirosyan has stepped up to the ring instead.
It may not be what you originally intended on watching but with it being Martirosyan's return to the ring after two years away, this is sure to be a fight that you cannot miss. Golovkin may be the big favorite with the bookies, but don't count out the Armenian-born veteran quite yet. He may yet walk out of the Stubhub Centre wearing those WBA and WBC middleweight belts.
