Anthony Joshua produced a stunning seventh-round knockout of Dillian Whyte as he overcame his toughest challenge yet to seize the vacant British heavyweight title at The 02.
Joshua, who also retained his Commonwealth crown, ended a bad-tempered clash after one minute and 27 seconds, initially staggering his bitter rival with a straight right before finishing him off with a ferocious right uppercut.
In initially worrying scenes, Whyte lurched over having been knocked to the canvas and once the fight had been waved off medics rushed into the ring to adminster oxygen. Whyte was soon back on his feet, however.
The 15th victory of Joshua's unblemished professional career avenged his defeat to the same opponent when they clashed as amateurs in 2009 and will taste sweet after having been branded a "scumbag" and "fake" by Whyte in the build up to their rematch.
