I believe it because no one involved has come out and called it bullshit.

Sparring partners have a duty of silence over anything that happens in sparring, its like a gentlemans code. Every boxer unless there is a personal gripe has respect for each other and they dont go out belittling someone they hurt. Plus, Spence would get kicked out of the gym for it I would have thought, or at least hed be wary of that happening.

Remember the Miranda kncking out Dawson? Well there is a video of Mirandas trainer on youtube explaining what happened. Like someone else has said, there is no smoke without fire.

What it means? Broner should tighten his defence up if he wants to achieve greatness. Would he have been able to come back against Mosley after taking that big right hand that Mayweather took? Maybe not. It will certainly effect his match making. Hes already fighting Malignagi
