Champion Golovkin closes in on deal to fight Chris Eubank Jr

LOS ANGELES (AP) Gennady Golovkin is closing in on a deal to defend his three middleweight title belts against Britain's Chris Eubank Jr.

Golovkin's promoter, Tom Loeffler, told The Associated Press on Thursday that the sides are ''working on finalizing details.''

Golovkin (35-0, 32 KOs) would travel to England in September to take on Eubank (23-1, 18 KOs), who holds Britain's 160-pound title.

Golovkin holds the WBC, WBA and IBF middleweight title belts. He has stopped 22 consecutive opponents since 2008, becoming the sport's most feared power puncher.

The fight would air on Sky Sports pay-per-view in Britain and on regular HBO in the U.S., where Golovkin lives and trains.

Golovkin was eager to fight Saul ''Canelo'' Alvarez next, but the Mexican star vacated his WBC middleweight title rather than take on Golovkin.
