According to British national newspaper The Sun Mexican born American Julio Diaz will face Amir Khan at the Motorpoint Arena in Sheffield on April 27.
Diaz told The Sun that not only has he signed the contract but he insist the British boxer will be in for a long and painful night.
"We are waiting for official confirmation from the Khan camp but as of now they have my contract which I have signed,” said Diaz.
"We have reached an agreement on a deal and everything is secure "
Diaz added: "There are a lot of weaknesses. He can’t take a punch and when he gets overwhelmed he tends to panic too much.
"I aim to make it a brawl. I won’t be too technical or too pretty but it will be a real fight."
