Report: Braun result triggered by medication

Brewers awaiting details on superstar outfielder's appeal

MILWAUKEE -- The website TMZ.com cited "sources directly connected with Major League Baseball" in reporting on Monday that star Brewers outfielder Ryan Braun's positive test under Major League Baseball's Joint Drug Prevention and Treatment Policy was triggered by medication for a private medical issue.

Braun reportedly is appealing the test result and faces a 50-game suspension if it holds up. Major League Baseball and the Brewers did not comment on the TMZ story. A spokesperson for Braun said he would not comment.

Brewers officials have mostly declined to comment on the matter since it leaked on Dec. 10 in an ESPN Outside the Lines report. On Monday, general manager Doug Melvin and assistant GM Gord Ash both said the club has been given no information about the timing of Braun's appeal.

"As bizarre as it may sound, we don't know anything," Ash said. "Nobody should have known anything at this point."

The TMZ report did not specify the medication or the private medical issue in question.

Braun's representatives at CAA Sports have retained prominent attorney David Cornwell to handle the appeal, and on Friday, Cornwell appeared on CNN to criticize the "breathless coverage" of the story.

"Confidentiality was breached here, and I think we will find -- I fully expect to be able to demonstrate that Ryan did not violate the substance policy of Major League Baseball," Cornwell told CNN. "And consequently, we shouldn't be dealing with this discussion at all, but at a minimum, I urge everybody to keep an open mind and give us the chance to make our case in private."
