Von Miller offers little on case

ENGLEWOOD, Colo. -- Denver Broncos linebacker Von Miller offered no details about his pending four-game substance-abuse suspension but was adamant that he doesn't smoke marijuana.

Miller repeatedly invoked the NFL's confidentiality clause to deflect questions during his session with reporters Wednesday. The All-Pro pass-rusher acknowledged his case is under appeal and promised he would provide some candid answers once the appeal is resolved.

The NFL is targeting mid-August as Miller's appeal, though it could be heard earlier, and a resolution to the case is expected before the regular season begins, a league source told ESPN NFL Insider Adam Schefter.

Though he wouldn't go into details of his case, Miller was asked if smoking marijuana was part of his life, and he answered, "Absolutely not."

It is unknown which substances Miller is accused of using. Under NFL policy, Miller would have to test positive for banned substances twice before facing a four-game suspension.

The Denver Post reported Monday that Miller tested positive for amphetamines and marijuana in 2011, his rookie season.

Miller said everything at training camp, which begins Thursday, will be business as usual, while he waits to hear if he'll be banned beginning Aug. 30 -- the day after Denver's final preseason game.

"It's tough, but I'm going to be me. I'm going to come here every single day with my teammates. We're focused on the task ahead. That's pretty much it," he said.

Miller said he didn't believe he had let his teammates down.

"Everybody has tough moments in their lives," he said. "I have great teammates. My teammates have been great for me."

Coach John Fox took the same tack, citing the confidentiality clause and offering virtually no details. The coach said Miller would practice with the first team until the Broncos receive any official word about the linebacker's status.

Miller said he can't wait for training camp to start Thursday and that he remains focused on football, as do the Broncos.

"Our focus is where it's always been -- that's coming out here and winning games," he said. "That's where it starts. It starts out here in practice when we get out there for practice and are running around and having fun. That's where we're going to keep our focus at."
