Freddie Roach offers US$1,000 to anyone who can floor Manny Pacquiao

Manny Pacquiao's trainer Freddie Roach has offered US$1,000 [£611] to any sparring partner that can knock down the Filipino.

Pacquiao, widely regarded as the world's best pound-for-pound fighter, started training on Tuesday at Hollywood's Wild Card club in Los Angeles ahead of his 14 November bout with the Puerto Rican Miguel Cotto.

"The money is still with me and I am telling the new sparring partners that they will be rewarded with $1,000 if they score a knockdown over Manny in sparring," Roach told the Manila Bulletin newspaper's website.

Pacquiao's last fight was his second-round knockout of Ricky Hatton in May.
