In a bout featuring two of the power punchers in the sport, Gennady Golovkin of Kazakhstan and David Lemieux of Canada have agreed to fight later this year in New York City. The middleweight fight is set on Oct. 17 at the Madison Square Garden, Golovkin announced on his official Twitter account.

Golovkin has the World Boxing Association middleweight crown while Lemiuex has the International Boxing Federation title in the same division. The October bout will unify the crowns in the middleweight division (160-pound limit).

The 33-year-old Kazakh also owns the International Boxing Organization and World Boxing Council titles in the middleweight division. Golovkin (33-0-0, 30 KOs) is rated the No. 1 fighter while the Lemieux, 26, (34-2-0, 31 Kos) is at No. 4 in the division rankings by Ring Magazine.

This will be Golovkin’s third bout in 2015 after knocking out Martin Murray and Willie Monroe Jr. in February and May, respectively. Golovkin is one of the most feared fighters in the sport defending his titles multiple times since becoming a world champion in 2010.

Lemieux has fought once this year, beating Hassan N'Dam N'Jikam in a 12-round unanimous decision last June, bringing him his first world.
