Gennady Golovkin will fight for the first time since losing to Canelo Alvarez when he meets Canadian Steve Rolls on June 8 at Madison Square Garden.
Golovkin (38-1-1, 34 KOs) has been out of action since Alvarez edged him in their rematch last September in Las Vegas.
The longtime middleweight champion could possibly meet Alvarez in a third bout between them, but first Golovkin will have to get by Rolls (19-0, 10 KOs) in a fight that was announced Tuesday.
The 12-round bout will be held at a maximum of 164 pounds, above the middleweight limit of 160 where Golovkin made a record 20 consecutive title defences.
It will be the Kazakhstani fighter's sixth time headlining at Madison Square Garden, which a week earlier is scheduled to host heavyweight champion Anthony Joshua's defence against Jarrell Miller.
