Gennady Golovkin and Kell Brook have both successfully come through their check weigh-in ahead of their world middleweight title clash at London's O2 Arena.

Both fighters weighed in under the limit of 160lbs on Friday and as per IBF regulations, they were allowed to put on an extra 10lbs ahead of a second weigh-in on Saturday morning.

Brook was first to hit the scales before officials made their way to Golovkin's camp, where the Kazakh came in under the designated limit.

Golovkin's WBC, IBF and IBO belts will be on the line as Brook steps up two weight divisions to try to dethrone arguably the world's best pound-for-pound fighter.
