It might be time to call it a career for Bryant “BY-BY” Jennings (24-3, 14 KOs) who suffered a twelfth round knockout loss to Oscar “Kaboom” Rivas (26-0, 18 KOs) on Friday night at the Turning Stone Resort in Verona, NY.

The bout was competitive with Jennings winning the early rounds, but the pressure of Rivas being troublesome, towards the end of the fight from say round eight onward, Rivas appeared to find a groove. Rivas dropped Jennings in the twelfth and final round twice with the second time being the stoppage.

The win sees Rivas picking up the IBF International and NABO heavyweight belts which Jennings held going into this bout 

This marks the second time in Jennings career he has been knocked out his previous loss was to Luis “King Kong” Ortiz.

Stevenson landed at will as his progression as a pro seems nearly complete as it feels like anyone who is not on the world level can not compete with Stevenson, a clean flurry floored Rosales, who was done despite a game effort to get to his feet.

After the fight, Stevenson called out IBF featherweight world champion Josh Warrington along with promoter Top Rank CEO Bob Arum.
