Jesse Hart and Joe Smith Jr. faced off before their highly anticipated 10-round light heavyweight showdown Saturday from Hard Rock Live at Etess Arena in Atlantic City (ESPN, 10 p.m. ET). Hart is attempting to gain a measure of revenge, as Smith knocked out his mentor and close friend Bernard Hopkins back in December 2016. (photos by Mikey Williams)

Hart (26-2, 21 KOs), who twice challenged for a super middleweight world title, will be making his second appearance at light heavyweight. Smith (24-3, 20 KOs) is making his second attempt at a world title, as he fell short in a spirited effort against WBA world champion Dmitry Bivol last March.
