Von Miller did not test positive for performance enhancing drugs or recreational drugs this year to trigger his NFL-imposed four-game suspension for violating of the league's drug policy, an NFL source said Friday.
There are numerous ways for a player to fail the policy. Missing a test or counseling session is a violation. Repeatedly showing up late for tests and behavioral issues also are considered compliance violations of the NFL's intervention program.
Miller was placed in the league's substance abuse program after he tested positive for marijuana during his rookie year in 2011.
Miller, who is appealing his suspension said on Wednesday that smoking marijuana is not a part of his life, but declined to talk about the case citing confidentiality.
Miller was the NFL's defensive rookie of the year in 2012 after he recorded 11? sacks and he bettered that in his second season of 2012 with 18? sacks.
This message was posted on Miller's Twitter account Monday afternoon: "Seeing reports abt 4 game susp. I know I did nothing wrong. I'm sure this'll be resolved fairly. Disapp. Broncos have 2 open camp like this."
If Miller loses his appeal, he likely would be replaced at starting strongside linebacker by Shaun Phillips. The former San Diego Charger signed a one-year, $1 million deal with the Broncos in late April.
