Floyd Mayweather has asked his fans on Twitter to vote on whether his next fight should be against Amir Khan or Marcos Maidana.
Khan signed a contract in December that put him in line for a possible super-fight with Mayweather this year, but the former Olympic silver medalist is still waiting to find out if he will face the unbeaten world light-middleweight champion.
Although a May showdown in Las Vegas was mooted for the British fighter, Mayweather, 36, also has the option of taking on Argentina's Maidana, who lost on points to Khan in 2011.
And the pound-for-pound world No 1 has sought the opinion of fans, writing on his Twitter account: "I'm going to let the fans vote. Tell me who I should fight next. Khan or Maidana?"
Khan, 27, has been holding out for a lucrative clash with Mayweather since suffering a scare in his dramatic points victory over Julio Diaz in Sheffield last April.
The Bolton man has a 28-3 record as a professional, while Mayweather has won all 45 of his bouts, including victory over the previously undefeated Ricky Hatton in 2007.
