Biogenesis whistle-blower: More than MLB players involved

Porter Fischer, a former employee of the now-infamous Biogenesis clinic in Miami, told ESPN's "Outside the Lines" that there are at least a dozen more athletes across numerous professional sports leagues that have yet to be exposed.

Fischer turned the Biogenesis clinic investigation into a national scandal when he turned boxes of documents over to the Miami New Times last year.

Fischer told "Outside the Lines" that at least one player from various leagues had received PEDs from Tony Bosch, the clinic's founder. In addition to Major League Baseball players, Fischer cited NBA players, NCAA players, professional boxers, tennis players and MMA fighters. According to Fischer, Bosch had no clients in the NFL or NHL.

"This isn't a 2013 thing or a 2012 thing; some of these people have been on the books since 2009," Fischer said.

Fischer started as a weight reduction patient of Bosch at the Biogenesis of Miami clinic before becoming an investor and marketing director. Bosch failed to repay a loan, leading to Fischer taking some documents to the New Times.

"When I would approach him for money, he'd be like, 'I don't have it. I don't have it.' And I was like, 'I want my money.' He was like, 'I'm Dr. Tony Bosch. What are you going to do about it?'" Fischer said. "So this is what I did about it."

Bosch's recent cooperation with MLB resulted in the Milwaukee Brewers' Ryan Braun agreeing to a season-ending 65-game suspension. Other suspensions, including for the New York Yankees' Alex Rodriguez, are expected within the next two weeks.
