Golovkin is legit, nothing wrong with his gloves, they have to be inspected before each and every fight. Let's face it, Golovkin is a very skilled fighter with great timing..............
I got info from GGGteam member, which was also confirmed in public by Steve Kim and Grigory Stangrit, that GGG busted GG ribs so that the latter had to leave next day. Kovalev admitted himself he got hit into a solar plexus and had to take a knee, for a source just scroll down a history of posts by me and you'll find it.
