With Pacquiao-Marquez IV unfortunately focused on allegations of illegal drug usage -- and for once, the allegations aren't pointed at Manny Pacquiao -- promoter Bob Arum has gone on record saying that despite claims otherwise, neither Team Pacquiao or Team Marquez suggested additional drug testing until the back-and-forth media trash talk last week.
From Luis Sandoval:
"Nobody suggested drug testing on either side until the issue came up this week. Because if the fighters had wanted drug testing I would've given the issue to the commission provided the commission would fund and the commission would've run pre-fight blood and urine tests. But nobody asked me."
Arum says he wouldn't have used USADA or VADA, and has the familiar stance that any additional blood/urine drug testing should be overseen by the commission, not by an outside agency. Given the recent USADA controversy in New York, where Erik Morales was allowed to fight Danny Garcia even though he failed two USADA drug tests (basically, he was tested until he finally passed, though apparently USADA is now trying to suspend Morales, for whatever that's worth). VADA has nailed both Lamont Peterson and Andre Berto this year on failed tests, and since the Berto test, they've basically gone missing besides 24/7 testing of Nonito Donaire, at Donaire's request.
Freddie Roach, who lobbed the allegations at Marquez and conditioning coach Memo Heredia, claimed that they'd offered to do additional testing for the fight, only to have Marquez turn them down. According to Arum, that is not the case.
