A few updates on Top Rank fights and fighters:

• Former featherweight titlist Evgeny Gradovich (19-1-1, 9 KOs) is set for his first bout since losing his world title by eighth-round technical decision to Lee Selby on May 30 in London. Gradovich was outclassed by Selby and unable to continue after suffering a cut from an accidental head-butt. Top Rank told ESPN.com that Gradovich, 29, of Russia, has been added to its Oct. 24 card at the CentruryLink Center in Omaha, Nebraska, which is headlined by junior welterweight titlist and 2014 fighter of the year Terence Crawford facing Dierry Jean. Gradovich will face journeyman Aldimar Silva Santos (19-8, 12 KOs), 34, of Brazil, in an eight-rounder. Silva Santos has won three bouts in a row against lesser opposition. He has previously lost to name fighters such as Jorge Arce, Juan Manuel Lopez and Jessie Magdaleno.

• In another fight on the Oct. 24 card, middleweight contender Matt Korobov, 32, has an opponent for his first fight in nearly a year. He is scheduled to face Josue Obando (13-7-1, 10 KOs), 25, of Mexico, in an eight-round bout. Korobov (24-1, 14 KOs), a 2008 Russian Olympian, has not fought since Dec. 13, when he faced Andy Lee for a vacant middleweight world title. Korobov was leading on all three scorecards when Lee rallied for a one-punch knockout in the sixth round.

• Junior featherweight prospect Jessie Magdaleno (21-0, 15 KOs), 23, of Las Vegas, will face Vergel Nebran (14-9-1, 9 KOs), 25, of the Philippines, in the scheduled eight-round main event of a “Solo Boxero Tecate” card on Oct. 17 at the Celebrity Theater in Phoenix. Light heavyweight prospect Trevor McCumby (19-0, 15 KOs), 22, of Glendale, Arizona, is slated to appear in the eight-round co-feature against an opponent to be determined.
