British fighter Amir Khan has announced he has signed a contract that could see him fight WBC welterweight champion Floyd Mayweather Jr. in the new year.
The 27-year-old, a former world champion and 2004 Olympic silver medallist, is waiting to learn whether Mayweather wants the fight.
The showdown could happen in Las Vegas on May 3, and Khan said on the Daily Mail website: "I am the one who signed the contract, I've signed my part of the contract, they've not signed theirs.
"If he wants to fight Amir Khan then he should sign it."
