Nonito Donaire seems likely to face Guillermo Rigondeaux in his next bout after a 4-0 year on HBO in 2012, but the Filipino star sounds like for the first time, he'll be requiring an opponent to engage in the random drug testing through VADA that he has made headlines for doing on an unprecedented scale in pro boxing. Dennis "dSource" Guillermo reports that Donaire will ask Rigondeaux to take the tests.

Donaire (31-1, 20 KO) is undergoing true random, year-round drug testing through the organization, 24/7/365, and is the only fighter in the sport to do so, and has done so voluntarily. Rigondeaux (11-0, 8 KO) wants the fight with Donaire by all accounts, and his strength and conditioning coach Memo Heredia has vowed to lead Rigondeaux to victory over Donaire after another of Heredia's clients, Jorge Arce, was knocked out in three by Donaire on December 15.

Donaire calls the request an "even trade" -- Rigondeaux gets his biggest opportunity as a pro, and Donaire makes sure (or as sure as one can be) that an opponent isn't cheating. To date, he has not forced opponents to undergo any additional testing.
