Mitchell Smith and Gary Corcoran both extended their unbeaten records with second-round stoppage victories at Bethnal Green’s York Hall.
Harrow Weald’s super-featherweight prospect Smith, 20, produced another scintillating display, this time destroying the previously unbeaten Mark Evans.
A hand injury meant Smith, whose record is now 8-0, was fighting for the first since winning the southern area title in September.
He twice floored rugged Welshman Evans, who felt he should have been allowed to continue after getting off the canvass for the second time.
Earlier in the evening, Wembley-based Irishman Corcoran also took his record to 8-0 by seeing off Faheem Khan.
The Pakistan-born Khan was floored in the first round of the light-middleweight contest and twice in the second, prompting the referee to stop the fight.
