Blood feud kills Super fight

LAS VEGAS, Nevada: Manny Pacquiao will not fight Floyd Mayweather next March because a blood testing stalemate wiped out what could have been the richest fight in boxing history, promoter Bob Arum said on Thursday.

The planned showdown between Filipino hero Pacquiao, a seven-division world champion, and unbeaten US star Mayweather could have brought each fighter as much as $40 million in a rare Las Vegas mega-fight spectacular.

Arum, Pacquiao's promoter, said Mayweather's request to have stricter US Anti-Doping Agency (USADA) testing methods, including possible random blood tests within days of the bout, killed any hope of reaching a deal.
