Khan ready for 'toughest' test against Judah

Amir Khan believes he will face the sternest test of his career when he goes head to head with Zab Judah in Las Vegas on Saturday night.

The 24-year-old is looking to add Judah’s IBF light-welterweight title to his own WBA belt at the Mandalay Bay Hotel and is under no illusions about the task in hand.
