Top Rank's CEO Bob Arum is getting impatient. He says everyone is waiting for Floyd Mayweather Jr. to sign a contract for a May 2 fight with Manny Pacquiao. Arum claims there is a contract that was sent for Mayweather's signature.

"Mayweather is not a boxer. Everybody knows that Manny accepted the terms that were negotiated for the fight [and the terms were negotiated by with everyone] including CBS and his management with Al Haymon, but Floyd Mayweather once again threw the fight because he's a chicken," said Arum told Azteca Sports.
