WBC light heavyweight champion Roy Jones Jr. scored a fourth-round knockout of former IBF and WBA champ Virgil Hill on Saturday night.
About a minute into the fourth round, Jones delivered two hard rights, the second a kidney punch that sent Hill to the canvas in pain. Hill got up, but referee Fred Steinwinder III stopped the bout.
Hill was taken to the hospital immediately after the fight, with what a ringside doctor said was apparently a fractured rib.
"I haven't heard a sound quite as devastating as that," Jones said of the punch that ended the fight.
Asked where the punch landed, and if it hit a bone, Jones said, "Under his left arm, I don't know where. If it hit a bone, it's broke. I almost broke my hand."
Jones connected on nearly half of the punches he threw (60 of 122) in his first bout since August. He also connected on 34 power punches, 23 more than Hill.
Jones improved to 36-1 with his 31st knockout. Hill, who lost his second straight bout, is 43-3.
On the undercard, Songul Oruc, a former world champion kick-boxer, made her professional debut with a third-round knockout of Jeanne Martinez. In a welterweight fight, Adrian Stone knocked out Desi Ford at the end of the fourth round of a scheduled eight-rounder.
SUPER-FLYWEIGHT: Gerry Penalosa retained his WBC title when the fight was stopped and called a technical draw in the second round because of a head butt by Joel Luna Zarate in Manila, Philippines.
