In brief: Mayweather fight rests on fans' vote
Boxing: Floyd Mayweather has asked boxing fans to vote on whether he should fight Amir Khan next or Marcos Maidana.
Khan (27) signed a contract in December that put him in line for a possible super-fight with Mayweather this year, but the Briton is still waiting to find out if he will face the unbeaten world light-middleweight champion
A May showdown in Las Vegas has been mooted as a possibility, but Khan is not the only contender for Mayweather, with Argentinian Maidana also an option for the 36-year-old American.
Pound-for-pound world No 1 Mayweather has sought the opinion of fans as to which of the two he should take on, writing on his Twitter account: "I'm going to let the fans vote. Tell me who I should fight next. Khan or Maidana?"
Bolton's Khan has a 28-3 record as a professional, while Mayweather has won all 45 of his bouts. The 30-year-old Maidana, who Khan beat in 2011, has a 35-3 record.
Wladimir Klitschko will defend his WBA, IBF, WBO and IBO heavyweight titles against Australian Alex Leapai in Oberhausen, Germany, on April 26.

Leapai defeated the previously unbeaten Denis Boytsov in November to become the WBO's mandatory challenger. The 34-year-old, who was born in Samoa, has a 30-4-3 record with 24 knockouts since turning professional in 2004.

Paired against American wild card John Mee, the 26-year-old Dubliner – who controversially opted out of Ireland's Davis Cup loss to Belarus, in Minsk, at the weekend – romped to a 6-3 6-3 victory.

Next opponent up for the 223-ranked Castleknock man is likely to be the No 2 seed, Russia's Alex Bogomolov Jr, who is ranked as high as No 98.
