A few notes from around the boxing world:

• With a hand injury rendering Russian contender Konstantin Ponomarev (30-0, 13 KOs) unavailable for a welterweight world title elimination bout ordered against Errol Spence Jr. (20-0, 17 KOs), the IBF has gone down its rankings to find the next leading available contender to order Spence to face for the right to become the mandatory challenger for the belt held by England’s Kell Brook (36-0, 25 KOs). That man is Leonard Bundu (33-1-2, 12 KOs), a 41-year-old native of Sierra Leone living in Italy. According to the IBF's Lindsey Tucker, the bout was offered to the fighters ahead of Bundu in its rankings but Jeff Horn and Lamont Peterson turned it down and Sammy Vasquez accepted at first but "when I asked him to put it in writing, he said he was going in another direction." Bundu was next and agreed to begin negotiating with Spence, 26, of Desoto, Texas. Their teams have until June 22 to make a deal or a purse bid will be called and would tentatively take place July 5, Tucker told ESPN.com.

• The Turning Stone Resort Casino in Verona, New York, which is hosting the Showtime-televised card headlined by Ruslan Provodnikov-John Molina Jr. on Saturday night (9 ET), announced plans for a tribute to Muhammad Ali, who visited the resort in October 1999 when his daughter Laila Ali made her professional debut at the resort. Featuring a quote from Ali -- "He who is not courageous enough to take risks will accomplish nothing in life," as well a photo of Ali taken during his visit to Turning Stone -- the memorial honoring his legacy will be displayed in the atrium of the arena on Saturday and then moved in a location where the boxers will see it on their way to the ring for every future fight at Turning Stone.

"To honor Muhammad Ali's incomparable legacy, we will prominently display this memorial so guests and boxers will be inspired by Ali's moving words and reminded of what it takes to be the best in the world," said Ray Halbritter, Oneida Nation Representative and Nation Enterprises CEO. "We also wanted to showcase the unique connection Ali and his family have to Turning Stone. Muhammad Ali transcended sports as a civil rights icon, and we hope that this memorial will serve as a fitting tribute."

• HBO announced plans for a special edition of "The Fight Game with Jim Lampley" to honor Muhammad Ali. The half-hour show will debut on HBO on June 14 (11 p.m. ET/PT) and "explore the remarkable achievements of one of the most significant figures of sports in the 20th century." The show will include a number of guests, including Hollywood legend Jack Nicholson, a longtime friend of Ali's.
