Khan knocks out Judah to win IBF crown

LAS VEGAS, (Reuters) – Amir Khan knocked out  American Zab Judah in the fifth round to add the IBF junior  welterweight title to his WBA super lightweight crown in Las  Vegas on Saturday night.
The end came with a bodyshot that crumpled Judah (41-7, 28  KOs) to his knees. Judah appeared to be complaining afterwards  that the punch was low but replays showed it was on the belt  line and legal.
Prior to the stoppage, Khan (26-1, 18 KOs), had been  dominant and aggressive, punishing Judah with a stiff left jab  and straight right hands.
