Oscar Collazo retained his Ring Magazine, WBO, and WBA world strawweight titles via KO after Jayson Vayson’s corner shockingly threw in the towel during the seventh round of their main event in California.
Collazo was gifted an early knockdown after catching Vayson with a glancing check right hook near the end of the opening round. The punch didn’t appear to affect Vayson, but he was just off-balance enough to hit the mat. Arguably, it could have been called a slip, but because the fall was preceded by a punch, the referee opted to rule it a knockdown for Collazo.
