Gennady Golovkin (35-0, 32 KOs) got what he asked for: a challenge. The reigning middleweight champion will get that when he steps onto enemy turf on Saturday in England to take on IBF welterweight belt holder Kell Brook (36-0, 25 KOs) with GGG's belts on the line.

Golovkin's camp is happy to get a tough opponent in the ring.

"With marquee names running in the opposite direction, we need to keep GGG busy," Golovkin's trainer, Abel Sanchez, told CBS Sports. "Everybody is dangerous on any night, but GGG is a special breed. Nobody from 154 to 168 lasts the distance."

Golovkin and Brook will head a two-bout card airing on HBO beginning at 5:30 p.m. ET. Before they step in the ring, IBF bantamweight champ Lee Haskins (33-3) will put his belt on the line against Stuart Hall (20-4-2). However, that fight will not be part of the HBO broadcast.
