A few notes from around the boxing world:

• Heavyweight titleholder Deontay Wilder (35-0, 34 KOs) was granted another optional defense by the WBC this week because mandatory challenger Alexander Povetkin won’t be ready until the spring. Wilder will make his third defense on Jan. 16 at the Barclays Center in Brooklyn, New York, according to Showtime, which will have live coverage. No opponent has been set yet. Wilder is a busy fighter. It will be his fourth fight in one year, a lot for a top fighter. He won his belt by lopsided decision against Bermane Stiverne on Jan. 17 and defended it on June 13 (ninth-round knockout of Eric Molina) and Sept. 26 (11th-round knockout of Johann Duhaupas).

• Japan’s Daiki Kameda (29-5, 18 KOs), who won world titles at flyweight and junior bantamweight, announced his retirement from boxing at 26 years old because of a detached retina in his left eye. Although it is the kind of injury that is usually easy to fix these days, Kameda said he was through. He was one of three fighting brothers, along with Koki and Tomoki, to all win world titles and they briefly held world titles simultaneously, the only time three brothers have ever done that. Koki Kameda announced his retirement about a month ago. Daiki Kameda has lost his past two bouts, both by split decision, including a junior bantamweight title unification bout to Liborio Solis in December 2013. Although, Solis could not win them because he had been stripped of his belt the day before the fight for failing to make weight.

• Top Rank promoter Bob Arum, with a great desire to make a fight between featherweight titleholder Vasyl Lomachenko and Guillermo Rigondeaux, recently stripped of his two junior featherweight belts for inactivity, said he hopes to make the fight and stage it at New York’s Theater at Madison Square Garden in early 2016. Lomachenko is the heavy favorite to defeat Romulo Koasicha in a title defense on Saturday night (HBO, 9:30 p.m. ET/PT) on the Timothy Bradley Jr.-Brandon Rios undercard at the Thomas & Mack Center in Las Vegas. Lomachenko-Rigondeaux would be a historically significant fight in that not only are they both among the best fighters in the world but it would also be the first time two boxers who both won two Olympic gold medals would meet.
