Sanctioned bare-knuckle boxing returns in the US........

On Saturday night, 10 bouts of bare-knuckle boxing, including one involving female fighters, will take place at the Cheyenne Wyo. Ice and Events Center.

The event, available on pay-per-view, is being promoted as the first legal, regulated and sanctioned bare-knuckle fight event in U.S. history. Back in Sullivan's day, there were no sanctioning bodies and few if any regulations.

The boxers will be allowed wraps around their thumbs and wrists but will not wear any protection over their knuckles....

Each bout is scheduled for five, 2-minute rounds, fought in a ring with rounded ropes instead of the traditional square.
