According to the Orange County Register, Diego Sanchez tested positive for marijuana after the Joe Riggs fight. This is surprising to me because normally things like this get out. Diego already paid the fine and served a three months suspension.
“UFC welterweight contender Diego Sanchez tested positive for marijuana after his first-round KO over Joe Riggs on Dec.13 at Miramar Marine Corps Air Station. Armando Garcia, the executive officer of the California State Athletic Commission, said Sanchez paid a $500 fine and served a three-month suspension, so he has been cleared to fight Josh Koscheck at UFC 69 on April7 in Houston”
