Boxing lost one highly anticipated rematch last week when Lamont Peterson tested positive for elevated testosterone levels leading up to his fight against Amir Khan and today fight fans continue to get bad news.

Twitchy has learned that welterweight champion Andre Berto has tested positive for steroids, which likely means his scheduled June 30th fight against Victor Ortiz will be canceled too.

Well-known steroid distributor and BALCO founder Victor Conte just happens to serve as Andre Berto’s nutritionist. Just seconds after the positive test leaked out, Conte blamed the test on trace contamination in a long Twitter rant.

While Conte is strongly accusing the positive test on contamination, he is also covering his butt by stating Berto may have been taking an illegal supplement he wasn’t aware of.
