Manny Pacquiao, the WBO world lightweight champion boxer, whose welterweight bout against rival Floyd Mayweather Jnr on March 13 was cancelled because of a row over blood testing, will now fight the Australian welterweight champion instead.
The fight against Joey Boxer, a kangaroo, will take place in Sydney on 1st April.
Pacquiao and Mayweather Jr have been ordered to submit to urine tests within 48 hours by the Nevada State Athletic commission, but the fight remains off.
The two boxers must submit to the tests or face possible fines or suspension by the Nevada regulator.
Boxer's unbeaten record of 489 wins, all by knockout, will be a severe test for the Filipino, who is as ugly as the day is long.
