Denver Broncos linebacker Von Miller is appealing a four-game suspension for violating the league's substance-abuse policy, but sources told USA Today that Miller did not fail a drug test.
"He didn't test positive for anything," an unnamed source told the newspaper.
The NFL's confidentiality rules may prevent the details of the proposed suspension from ever becoming public. But it appears there's more to the story that what is evident on the surface.
It's possible to violate the league's substance-abuse policy without testing positive for a drug. For example, a player may refuse to take a test or he could have submitted a diluted sample.
Therefore, even if Miller did not test positive, it's still possible for him to lose his appeal and be suspended.
