BIRMINGHAM, Alabama Virgil Hunter was busy broadcasting fights Saturday night when Amir Khan and Manny Pacquiao confirmed through social media that they’ve come to an agreement to fight April 23. Once he learned the fight figures to happen in two months, Hunter had a lot less hesitation about Khan taking this difficult assignment than when Khan agreed to fight Canelo Alvarez. Hunter considers Khan’s familiarity with Pacquiao and the fact that England’s Khan will be the bigger boxer in this fight as advantages he didn’t have against Alvarez.
