Lehlohonolo Ledwaba vs. Manny Pacquiao
Filipino Manny Pacquiao defeated South African Lehlohonolo Ledwaba via technical knockout for the IBF junior featherweight title.

The eight-round fight is generally considered as a significant event for both boxers' careers. At the time, Ledwaba had been ranked as one of the top pound-for-pound boxers, and was scheduled for a bout with Mexican Enrique Sánchez. However, Sanchez was injured two weeks before the undercard bout, and matchmaker Sampson Lewkowicz replaced him with Pacquiao, who would thus have his debut in the U.S.. The fight also became the first match of Pacquiao to have Freddie Roach as his coach.

Ledwaba considered the bout to be the most difficult fight in his career. He remarked that during the bout, he "tried almost everything. I'm a boxer who used to think. I always tried to outwork an opponent, but it was totally different against Manny. [...] I was flat-footed, but he was on his toes all the time, so he was hard to hit." His promoter Rodney Berman later expressed the thought that Ledwaba's defeat to the then-unknown Pacquiao caused him to lose motivation in boxing; Ledwaba did not have anymore world level fights after the match, and retired from the profession by 2006. For Pacquiao, he won $40,000 for his victory, and later stated that alongside his other early fights, he fondly remembers his fight against Ledwaba because "[t]hat's the one that got me here to the U.S. and after that my career really started."
