According to sources in Puerto Rico, featherweight contender Jonathan Oquendo (23-3, 16 KO's), who on Saturday night scored a fourth round knockout of Mexico's Miguel Tamayo (14-7-2, 12 KO's), could be fighting again in October 12 with highly regarded Ukrainian prospect Vasyl Lomachenko - who will make his professional debut on the Juan Manuel Marquez vs. Timothy Bradley HBO Pay-Per-View at the Thomas & Mack Center in Las Vegas.

Lomachenko, who was recently signed by Top Rank, won gold medal in the 2008 and 2012 Olympic Games and has one of the most impressive amateur runs in boxing history. In the 2012 games, he even defeated hot Puerto Rican prospect Felix Verdejo (14-9), who himself was signed by Top Rank in 2012. In the 2007 World Championships, Lomachenko beat Abner Cotto 26-9 en route to winning the silver medal.
