A few notes from around the boxing world:
• The mandatory fight between cruiserweight titlist Yoan Pablo Hernandez and interim titlist Victor Emilio Ramirez finally has a date and location: Oct. 2 in Buenos Aires, Argentina, Ramirez’s home country, according to the IBF. The fight has bounced around the calendar but now it is set. Ramirez claimed a vacant interim belt with a decision win against Ola Afolabi in April in a fight approved for the interim title because Hernandez, a Cuban defector based in Germany, has been for 13 months because of a right elbow injury. Now that Hernandez, a southpaw, is ready to return his must face Ramirez. Hernandez (29-1, 14 KOs), who turns 31 next month, will be making his fifth title defense.
• Middleweight Matt Korobov, the former standout Russian amateur and 2008 Olympian, was slated to return to action Sept. 11 on the non-televised portion of Top Rank’s truTV card at the Cosmopolitan in Las Vegas, but has been shifted to fight Oct. 24 in Omaha, Nebraska, on the untelevised portion of junior welterweight titlist Terence Crawford’s defense against Dierry Jean. One of the reasons for the switch, according to Top Rank vice president Carl Moretti, was because Korobov “made such a hit there last when he fought.” Indeed, Korobov (24-1, 14 KOs), 32, made a good fight with Jose Uzcategui in Omaha on a previous Crawford undercard in June 2014 and won a unanimous decision. Korobov, who does not have an opponent yet, 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.
• The mandatory rematch between secondary heavyweight titleholder Ruslan Chagaev and Fres Oquendo is set for Oct. 17 at Sparkassen Arena in Kiel, Germany, Oquendo co-promoter John Wirt of Square Ring told ESPN.com. In June 2014, Oquendo traveled to Grozny, Russia, and lost a majority decision to Chagaev for a vacant secondary title. Wladimir Klitschko is the recognized world champion. Oquendo had a rematch clause in the contract but Chagaev’s team set up another fight first. Oquendo’s team sued and won an injunction to stop the fight and then made a deal to allow Chagaev (34-2-1, 21 KOs), 36, a native of Uzbekistan living in Germany, to go through with a defense against Francesco Pianeta as long as the winner agreed to fight Oquendo (37-8, 24 KOs), 42, next. Chagaev knocked out Pianeta in the first round on July 11.
