Yoenis Tellez needed nearly all 10 rounds this time, but he knocked out another more experienced opponent Friday night.

The talented junior middleweight prospect viciously finished fellow Cuban Livan Navarro with a left hook in the 10th and final round of their 154-pound bout on the Jake Paul-Andre August undercard at Caribe Royale Orlando in Orlando, Florida.

In his previous fight, Tellez stopped Spain’s Sergio Garcia in the third round on the Terence Crawford-Errol Spence Jr. undercard July 29 at T-Mobile Arena in Las Vegas. Garcia (34-3, 14 KOs) hadn’t been beaten by knockout or technical knockout before he encountered Tellez.
