Wales' Lee Selby (23-1, 8KOs) will defend his IBF featherweight title against former world champion Jonathan Victor Barros.

Argentine Barros narrowly beat Satoshi Hosono on a split decision in Tokyo, Japan to become the mandatory challenger for Selby's title. The scores were Barros, 117-111 and 116-112, and 115-113 for Hosono.

The fight was being planned for December, but Barros (41-4-1, 22 KOs) suffered a cut over his right eye against Hosono (32-3-1, 21 KOs) and that could push to next year.

The 29-year-old Welshman has not fought since his second successful title defence against American Eric Hunter at London's O2 Arena in April 2016.

Selby's UK promoter Eddie Hearn has criticised the fighter's inactivity, with the Argentine having only fought twice in 17 months.

Barros managed to eventually put a belt around his waist, claiming a vacant featherweight title in a Dec. ’10 win over Irving Berry. His reign managed to last long enough to post wins over Miguel Roman and in his first fight with Caballero, albeit in a controversial decision before losing the belt in their Oct. ’11 rematch.

The loss to Caballero was the lone time he’s come up short at home. Unfortunately, he is also winless outside of Argentina and neighboring Uruguay, with losses to Yuriorkis Gamboa (March ’10 in Germany), Juan Carlos Salgado (Aug. ’12 in Mexico) and Mikey Garcia (Nov. ’12 in Las Vegas) all taking place on the road.

His showdown with Hosono marked the first trip to Japan for the 32-year old Argentine boxer.
