Mayweather-Alvarez in theaters

A few notes from the boxing world:

• Fans who like watching the biggest pay-per-view fights at a movie theater can do so again for the year's biggest bout, the Sept. 14 junior middleweight unification bout between pound-for-pound king Floyd Mayweather Jr. and Canelo Alvarez. NCM Fathom Events and Golden Boy Promotions have partnered in recent years to bring fights to the big screen and they are doing so again to make "The One" pay-per-view card available at nearly 550 movie theaters across the country. The HD presentation will be the same as the home Showtime pay-per-view telecast, including the much-anticipated junior welterweight championship fight between Danny Garcia and Lucas Matthysse. To find the theater closest to you and for ticket prices (which vary by theater but are far cheaper than the pay-per-view price tag) check out NCM Fathom’s website at www.FathomEvents.com for the list.

"I love that so many of my fights have been shown in movie theaters," said Mayweather, who has had all of his fights since 2009 shown in theaters. "It's something that I wanted to bring to the fans for a long time. It’s my job to give the fans the best entertainment possible."

• In his return from a fractured hand, featherweight Gary Russell Jr. (22-0, 13 KOs), the 2011 ESPN.com Prospect of the Year, will face Juan Ruiz (23-11, 7 KOs), according to Golden Boy. The fight is due to take place Aug. 9 on the untelevised portion of the Showtime "ShoBox" card headlined by heavyweight prospect Deontay Wilder against former titlist Sergei Liakhovich at the Fantasy Springs Resort Casino in Indio, Calif. As usual, Russell and his team are not looking to take any chances whatsoever as he faces yet another woefully weak opponent. Ruiz has lost six fights in a row and nine of his last 10.

• Former junior welterweight titlist Amir Khan, who likely will challenge Devon Alexander for a welterweight belt in December, announced that he has parted ways with longtime business manager Asif Vali, who was at his side for years. Khan announced the separation was by "mutual agreement." Other than Khan's family members, Vali was the most trusted member of Khan’s inner circle. "I would like to sincerely thank Asif for all his hard work and wish him the very best for the future," Khan said. Said Vali, "I would like to wish Amir and his family the very best for the future. I have enjoyed my time working with them and plan to remain in boxing as I explore new exciting ventures."
