Top Rank cash cow Julio Cesar Chavez Jr. has failed his post-fight drug test in Nevada from his November 14 win over Troy Rowland. Dan Rafael has the details:

Middleweight Julio Cesar Chavez Jr., the son of the former three-division champion and Mexican icon, tested positive for a banned substance in conjunction with his Nov. 14 fight against Troy Rowland, according to the Nevada State Athletic Commission.

Executive director Keith Kizer said Saturday that Chavez, who tested positive for Furosemide, a diuretic, faces a fine and suspension.

...

The commission filed a formal complaint on Tuesday against Chavez. He has 20 days to respond, which will be followed by a hearing at a date to be determined. If Chavez does not respond to the complaint, the commission may reach a decision in his absence.

If the commission upholds the test result, which it usually does, the result of the fight would be changed to a no decision.

Furosemide (commonly known to most as Lasix) isn't a problem by itself, but it's banned because it is used as a masking agent for other drugs, which is most likely the case here.

Top Rank offered this statement:

"I think it was an innocent mistake, one that the Nevada commission will have to deal with, as well as Chavez," said Top Rank's Carl Moretti. "I don't think he knew diuretics were banned by the Nevada commission."

So, believe what you will, but chances are Chavez faces a suspension and the win over Rowland, already a painful memory for those who sat through it, will be changed to a no contest.
