Jack on Bivol, Vacating: I'm Not Ducking a Guy With 11 Fights
Jack told ESPN.com for a story posted Monday afternoon that he didn't give up his WBA world light heavyweight title Saturday because he doesn't want to fight the hard-hitting Bivol . The former WBC super middleweight champion said he relinquished his version of the WBA's 175-pound championship as part of an agreement he made with the WBA before he fought then-champion Nathan Cleverly last month.
