Judah (41-6), scored the 28 stoppage of his career to pick up the vacant IBF light-welterweight title after referee Samuel Viruet stepped in as barrage of punches from the southpaw followed a crushing left hand counter that dropped Mabuza and the fight was stopped 59 seconds into the seventh round.
Mabuza, 31, showed he was no pushover in the earlier rounds of the contest, putting Judah down in the fourth with a right hand and rocking him in the sixth, but Judah used all of his world title experience to come through any hairy moments and came away victorious.
BRONER
Also on the Newark card, Adrien “The Problem” Broner edged a cagey ten round contest against former WBO super-bantamweight champion Daniel Ponce De Leon to score his 20th straight win. The 21 year-old remains undefeated after the judges handed him a 99-91, 96-94, 96-94 victory.
Daniel Jacobs scored his second successive stoppage since losing for the first time in his career against Dmitry Pirog for the WBO middleweight title, by blasting out Robert Kliewer in just under two minutes to claim his 19th KO in 22 victories.
Heavyweight prospect Seth Mitchell improves to 21-0-1 after pummelling Charles Davis for his 15th career stoppage. The Maryland-based 28 year-old dropped his opponent in the first round, before Davis hit the canvas three times in the second and the referee waived off the fight.
