This is bigger than your normal PED suspension:
Byrd, a free agent, will be on the restricted list until August 20.
This is notable for more than the fact that Byrd is a bigger name than you usually see on the suspension list. Byrd has quite famously trained with former BALCO figure Victor Conte, who has claimed for years to have seen the light and to only work with legal and non-banned substances. It has led to much talk about Byrd being somewhat reckless in his choice of trainer and has caused many to speculate that Byrd was under closer scrutiny by the league due to his association with Conte.
Whether Byrd got the substance from Conte or whether it was an intentional thing or a situation of something being adulterated is not known. But it’s certainly going to lead to more than just this suspension. Someone -- likely Conte -- is gonna have some stuff to say pretty soon, I’d wager.
UPDATE: The drug Byrd tested positive for -- Tamoxifen -- is an estrogen blocker, not a PED itself. It’s on the banned list, however, because it’s used by people who take steroids to mitigate the side-effects.
Bob Nightengale reports that Byrd has issued a statement regarding his positive test, apologizing, but saying that the drug was used for “a reoccurrence of private surgery he had years ago.” This echoes the statements of others who have been caught using estrogen blockers, most of whom have said it was for medical issues.
