Round 5
The gulf in athleticism is quite staggering here with Khan just making Judah look hopeless by working with such verve and dynamism. Khan is taking apart Judah with real ferocity, landing fast combinations at will. Judah's game is coming part under the pressure — desperately trying to hold and complaining to the referee. The end comes when Khan follows up a straight right with a punch to the body that drops Judah hard at 2:40, and Judah doesn't get up before the 10-count.
Replays show that the punch was very close to the belt-line, some angles showing it low but the side-on shot seemed to suggest it landed cleanly. Slight note of controversy aside, a dominant performance nonetheless from Khan. After a disappointing performance against Paul McCloskey he seemed back to his best tonight.
