A couple of notes from around the boxing world:

• The IBF ordered a final welterweight eliminator to produce the mandatory challenger for Kell Brook between Timothy Bradley Jr. and Amir Khan. However, according to the IBF, Khan declined to participate. Instead, Khan appears headed to a May 30 bout against former titleholder Chris Algieri. Khan could have had a June 13 shot at Brook without fighting the eliminator, but he also declined that bout, a huge fight in their home country of England. Since Khan declined, the next ranked fighter who will be offered the opportunity to face Bradley in the eliminator is Frankie Gavin, Khan's countryman.

• Gary Russell's fourth-round knockout of Jhonny Gonzalez to win a featherweight world title in dominant fashion Saturday night at the Palms in Las Vegas averaged 519,000 viewers and peaked at 575,000 viewers, according to Showtime. Overall, the two-fight broadcast, which also included junior middleweight Jermell Charlo's close decision win against Vanes Martirosyan, averaged 377,000 viewers. Those are not great figures but also not bad considering the sports world was mainly focused on NCAA men's basketball tournament regional finals on CBS that day.
