Von Miller is expected to be suspended for at least six games. Miller is still hoping to negotiate a four-game suspension.
Miller violated the NFL's substance abuse policy.
Miller's hearing to appeal a previous four-game suspension scheduled last week had been delayed.
Miller reportedly did not fail a drug test to trigger this suspension, but he was already in the NFL's drug program due to a failed test in his rookie season.
Miller is ranked No. 9 in the NFL Network's Top 100 Players of 2013.
