A few notes from around the boxing world:
• The much-anticipated all-Brooklyn, New York, showdown between secondary middleweight titlist Daniel Jacobs and former titleholder “Kid Chocolate” Peter Quillin is penciled in for Dec. 5 at the Barclays Center in Brooklyn, a source with knowledge of the details told ESPN.com. It has not been determined which network will carry the fight, but it’s a good bet for Showtime or a Premier Boxing Champions card on NBC or ESPN. However, for the fight to take place, Quillin (31-0-1, 22 KOs) must first defeat unknown and untested Michael Zerafa (17-1, 9 KOs) on Sept. 12 (CBS). In his last fight, Quillin fought to a split draw with world titleholder Andy Lee but was not eligible to win the belt because he did not make weight. Jacobs (30-1, 27 KOs) made his second defense on Aug. 1 with Quillin at ringside, stopping Sergio Mora in the second round when Mora broke his ankle and was unable to continue.
• Middleweight Matt Korobov (24-1, 14 KOs), 32, the former standout Russian amateur and 2008 Olympian, will return to the ring on Sept. 11 at the Cosmopolitan in Las Vegas, according to Top Rank. Korobov has not boxed 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. Korobov will fight on the non-televised undercard in a scheduled eight-round bout against an opponent who has yet to be determined. The truTV-televised portion of the card will be headlined by the junior featherweight fight between top prospect Oscar Valdez (16-0, 14 KOs) and former title challenger Chris Avalos (26-3, 19 KOs). In the co-feature, super middleweight prospect Jesse Hart (17-0, 14 KOs) will fight Aaron Pryor Jr. (19-8-1, 12 KOs).
• Popular brawler Alfredo Angulo (23-5, 19 KOs), 33, of Mexico, will be in action against an opponent to be named later in a super middleweight bout Aug. 29 at the Staples Center in Los Angeles. His fight will be part of the Premier Boxing Champions card (ESPN) headlined by the much-anticipated featherweight showdown between Leo Santa Cruz (30-0-1, 17 KOs) and Abner Mares (29-1-1, 15 KOs). But Angulo has looked very bad in recent fights. After he lost three fights in a row, to Erislandy Lara and Canelo Alvarez by knockout and a decision to James De La Rosa, Angulo struggled terribly in a fifth-round knockout of journeyman Delray Raines on June 6.
