Rafael Marquez back in action May 5

Zanfer Promotions announced that former bantamweight and junior featherweight champ Rafael Marquez (40-7, 36 KOs), idle since a competitive decision loss to then-junior featherweight titlist Toshiaki Nishioka in October, will return May 5 in his native Mexico.

Marquez, who will fight on a card in Tijuana that will be headlined by popular female junior featherweight Jackie Nava, will face Nicaragua's Eusebio Osejo (20-10-2, 7 KOs). Also on the card, former interim junior lightweight titlist Humberto Gutierrez (28-3-1, 20 KOs) will return for his first fight -- opponent to be determined -- since he was stopped in the fourth round by titleholder Tahahiro Ao in Japan in an April 2011 title bout.
