Herring will defend his WBO world title against undefeated former featherweight world champion Stevenson from the State Farm Arena in Atlanta.

Herring (23-2, 11 KOs), a U.S. Marine Corps veteran who captained the 2012 U.S. Olympic boxing team, has made three defenses of his crown including a 6th-round stoppage of former two-division champion Carl Frampton his last time out.  

He now faces 2016 U.S. Olympic silver medalist Stevenson (16-0, 8 KOs), a former WBO featherweight world champion who vacated the title last year to move up to junior lightweight. Stevenson looks to become a two-division champion at just 24 years young.
