Danny Garcia and Lamont Peterson will warm-up for a potential unification fight by appearing on the same bill on August 9.
Garcia will put his WBC and WBA light-welterweight titles on the line when he takes on Rod Salka at Brooklyn's Barclays Center.
And at the same venue, IBF champion Peterson will face Edgar Santana knowing victory will put him in line to face the undefeated Garcia.
I'm really excited about this fight and about making a statement to the boxing world that I'm the true junior welterweight world champion, Peterson said.
I know Danny will be watching me and I'll be watching him. After August 9, there will be only one fight to make at 140 pounds.
Garcia, who stopped Amir Khan in the fourth round to win the WBA title in July 2012, is focusing solely on his next opponent - with fellow American Rod Salka coming into the contest with a 19-3 record.
I'll be ready, Garcia said. I'll give my fans another great show.
There will be a third world title up for grabs on the night, with Jarrod Fletcher and Daniel Jacobs clashing for the vacant WBA middleweight belt.
Fletcher, part of the Australian Olympic squad in 1008, has won 18 of his 19 bouts, while Jacobs (27-1) makes his returning after a 19-month lay-off fighting cancer.
This whole comeback has been a dream so far, and what better way to keep it going than with a world title fight? said Jacobs.
This is the fight I've been waiting for and no one will keep me from that belt.
