NEW YORK - British boxer Amir Khan will be in the arena when Devon Alexander defends his world welterweight title, just not in the ring as the US champion had originally intended. Khan will serve as a ringside commentator for Showtime for the telecast of the card at Brooklyn's Barclays Center, replacing Paulie Malignaggi, the regular commentator who will instead be in the ring against Zab Judah in a main-event showdown of hometown heroes. With a deal almost set, Khan decided against fighting US southpaw Alexander for the International Boxing Federation welterweight crown amid speculation that the Briton will be the next opponent for unbeaten Floyd Mayweather next May. Khan and Mayweather camps have said no such deal is in place, but neither fighter has announced his next opponent.–AFP
