On Friday, Khan, idle since getting dropped in a shaky decision win against faded former lightweight titlist Julio Diaz last April, sent a series of tweets in which he said he had been passed over by Mayweather.
"No response from Mayweather or his team," Khan tweeted. "Fights not happening. I should of taken the title fight last December against Alexander. Very disrespected by [Mayweather's] team. Wasted my time. Good luck to Maidana against Mayweather. Can I apologize to the thousands of people who are let down. You me and everyone wanted the Mayweather fight. He's running scared."
After Maidana defeated Broner, Broner had a contractual option for a rematch, which he exercised. However, powerful adviser Al Haymon, who works with Mayweather, Maidana and Broner, worked things out so Mayweather could face the opponent of his choice.
"What it took was conversations with all the parties and, in the end, all the parties were happy with the outcome," Schaefer said. "Adrien will certainly have another big fight ahead of him, but the situation [with the Maidana-Broner rematch] was worked out among the involved parties. Adrien wasn't really jumping up and down about it, but it was explained to him and worked out. I have to thank Al for making it happen."
