Denver Broncos star linebacker Von Miller is facing a four-game suspension for violating an NFL policy, ESPN's Adam Schefter reported on Monday.
Schefter tweeted that the case is currently in the appeals process.
Citing "a source with knowledge of the situation," Mike Klis of the Denver Post reported that Miller is facing a suspension for "violating the NFL drug policy."
The report of Miller's possible suspension comes not long after the organization suspended two executives without pay for their recent drunk driving arrests.
A two-time Pro Bowler, Miller finished the 2012 season with 18.5 sacks and six forced fumbles. Denver has already lost another star pass rusher, three-time Pro Bowler Elvis Dumervil, in free agency after a faxing debacle.
UPDATE: Klis tweeted later on Monday that Miller had a positive drug test in 2011.
According to NFL source, #Broncos LB Von Miller tested positive for amphetamines and marijuana during his rookie season of 2011.

More from the Associated Press:
ENGLEWOOD, Colo. (AP) — A person with knowledge of the situation says Pro Bowl linebacker Von Miller will miss the first month of the season for violating the NFL's drug policy, pending an appeal.
The person spoke to The Associated Press on condition of anonymity because the league hasn't announced any punishment.
ESPN first reported the pending discipline of Miller, who didn't answer calls to his cellphone Monday from The Associated Press.
The league has a confidentiality clause on such cases. Broncos spokesman Patrick Smyth said the team is unable to provide any comment.
Miller was the league's Defensive Rookie of the Year in 2012 with 11½ sacks and he topped that last season with a franchise-record 18½ sacks while making it to his second straight Pro Bowl.
