The main event of Eddie Hearn's Matchroom Boxing USA card now has added significance.

Former welterweight champion Jessie Vargas and Thomas Dulorme will not only battle for the WBC Silver welterweight title at the Wintrust Arena in Chicago on Oct. 6, airing exclusively on DAZN, but the winner also sets himself up to face WBC champion Shawn Porter.

“Jessie is the leading contender in the WBC rankings and I am very confident that victory on October 6 will lead him to the mandatory position for Shawn Porter,” said promoter Eddie Hearn. “That’s a great fight that we would be very interested in, but first he must win the Mexico vs Puerto Rico battle in Chicago.”

Vargas (28-2-1, 10 KOs), who is ranked third by the WBC, put on one of his best performances in recent memory when he went to a draw in April with Adrien Broner. The 29-year-old Vargas goes into this all-important contest 2-2-1 in his last five fights, though the losses were to Timothy Bradley and Manny Pacquiao. While the chance to become a two-time welterweight titleholder is the goal, Vargas is keeping his eye on the prize.

“My focus has to be solely on Thomas Dulorme,” Vargas said. “This man is no walk in the park, he fights with his heart and always gives it his all, but I have prepared properly [to] record a tremendous victory. It's going to be a great show and I'm proud to be headlining it."

He added: “This is the first step in the new phase of my career. As a fighter, it's always best to have fights lined up and have a clear plan, have a promoter that shows you, 'you are going to fight three times in 12 months.' And when you get that certainty, you know you have a couple of weeks off after a fight and then you are into another training camp to give the fans another great fight. I am still young and I have plenty of years left in me at the very top level. I'm truly excited."

Dulorme (24-3, 16 KOs) is a former junior welterweight title challenger, losing to arguably the best boxer in the world, Terence Crawford, by sixth-round TKO in April 2015. In his most recent outing, the 28-year-old lost a narrow decision to Yordenis Ugas after losing two points for repeated low blows. The biggest win in Delorme's career was over former WBO junior welterweight titleholder DeMarcus "Chop Chop" Corley in June 2011.

Porter (29-2-1, 17 KOs) captured the vacant title in beating Danny Garcia by unanimous decision on Sept. 8.

Also on the Oct. 6 event, heavyweight contender Jarrell "Big Baby" Miller takes on Tomasz Adamek, a former light heavyweight and cruiserweight champion. The card will also have two title fights, as IBF light heavyweight titlist Artur Beterbiev defends his belt against Callum Johnson and WBA super bantamweight champ Daniel Roman faces Gavin McDonnell.
