A few notes from around the boxing world:
• No deal is done but former two-time heavyweight title challenger Chris Arreola is atop the short list to get a shot at world titleholder Deontay Wilder (36-0, 35 KOs) this summer, according to a source involved in organizing Wilder's next bout. Wilder's fight could take place as soon as July 16 or take place in August. Wilder was supposed to face mandatory challenger Alexander Povetkin on May 21 in Moscow, but the fight was called off after Povetkin tested positive for the banned substance meldonium nine days before the bout. With the fight off, the WBC approved Wilder to take an optional defense and Arreola (36-4-1, 31 KOs), who, like Wilder, is with manager Al Haymon, quickly emerged as the leading candidate. But Arreola has fallen off from where he once was as a top contender and is 1-1-1 with a no decision in his last four fights. His last fight was a questionable decision win against Travis Kauffman on Dec. 12 that was changed to a no decision after Arreola tested positive for marijuana following the fight. He was fined and suspended 90 days, which ended in mid-March.
• With representatives for cruiserweight world titleholder Krzysztof Glowacki (26-0, 16 KOs), who is promoted by Warriors Boxing, and mandatory challenger Oleksandr Usyk (9-0, 9 KOs), who is with K2 Promotions, unable so far to make a deal, the WBO on Friday ordered a purse bid. It is scheduled to take place June 9 at the Affinia Hotel in Manhattan. Minimum bid is $300,000. Glowacki, 29, of Poland, won the belt in dramatic comeback fashion when he knocked out Marco Huck in the 11th round last August. He made his first defense against former titlist Steve Cunningham in April and won a unanimous decision in another entertaining fight. The 29-year-old Usyk, the 2012 Olympic heavyweight gold medalist for Ukraine, had to withdraw from an April 23 tune-up fight because of a foot injury.
• Middleweight titlist Daniel Jacobs (31-1, 28 KOs), 29, of Brooklyn, New York, has not been in the ring since destroying neighborhood rival and former titlist Peter Quillin in 85 seconds on Dec. 5. He is due back in action to defend his secondary title for the fourth time on July 30 on Showtime in the co-feature of the Leo Santa Cruz-Carl Frampton featherweight title bout at Barclays Center in Brooklyn. His opponent is not set yet but he likely will face former junior middleweight titleholder Sergio Mora in a rematch, according to promoter Lou DiBella, who stressed that no deal was done yet. Jacobs knocked out Mora in the second round last August because Mora broke his ankle when he got knocked down and could not continue. "It's being discussed but nothing is being announced because nothing is done yet. Things are fluid. We hope to have things wrapped up and announced by the end of next week," DiBella told ESPN.com. A proposed Jacobs-Andy Lee fight went by the wayside because it was too expensive to serve as an undercard bout for the already-expensive Santa Cruz-Frampton main event.
