LAS VEGAS, NV - WBA junior welterweight champion Amir Khan is getting in some final training at the IBA gym. Khan prepares for Saturday's unification against IBF champion Zab Judah at the Mandalay Bay in Las Vegas. During some work with the pads, Khan's trainer Freddie Roach appears to have not been quick enough and got checked on the chin. Not first time or the last time, that Roach has been caught. The trainer has said that his other fast-handed boxer, Manny Pacquiao, caught him a few times over the years.
