Boxer Amir Khan ready to defend World title

Britain's Amir Khan plans to wake up American boxing fans to his skills on his Las Vegas debut tonight by turning out the lights on Marcos Maidana's title dreams.

Khan will defend his World Boxing Association super-lightweight title against the Argentine mandatory challenger in what is expected to be the first step toward unifying titles in the division.

Khan will face Maidana for the right to tackle the winner of January's fight between unbeaten US fighters Devon Alexander and Tim Bradley.
