The time for a Prescott rematch is longer over now. Prescott losing against 2 of his last 4, and looking pretty **** in every fight since the Khan fight also makes this less interesting. Khan moved up to better opponents and beat them handily, irregardless of if they were punchers or not. Prescott wants the fight for the money, he needs the fight. Khan has zero reason to go back to Prescott, financially or even mentally. If he beats Prescott it won't erase what happened.
