Mandalay Bay, Las Vegas - For the WBO welterweight championship, Terence Crawford (38-0, 29 KOs) picked up a tenth round stoppage of two-time champion Shawn Porter (31-4-1, 17 KOs) in an action fight.
It marked the first time that Porter had been stopped in his pro career.
The end came during the tenth, as Crawford was stalking and caught Porter with a big shot as he walked in - which scored the first knockdown. Porter got up, came in to trade punches with Crawford and was dropped for a second time from a combination of shots. Porter got up again, but his corner, specifically father and head trainer Kenny Porter, threw in the towel to stop the fight.
