JAMEL HERRING CREDITS TERENCE CRAWFORD AND MAURICE HOOKER FOR HELPING HIM PREPARE FOR LAMONT ROACH CLASH

Under the bright lights, above where a pitcher’s mound normally stands, Jamel “Semper Fi” Herring will enter the ring for the first time as a champion. Herring, who makes the first defense of his WBO junior lightweight world title against Lamont Roach Jr. Saturday evening (10 p.m. ET, ESPN+) at Chukchansi Park (home of the Triple-A Fresno Grizzlies), is a U.S. Marine Corps veteran who served two tours of duty in Iraq.
