Denver Broncos linebacker Von Miller will likely be suspended six games by the NFL, according to ESPN.
The NFL could announce the suspension Monday.
Miller was originally suspended four games for violating the NFL’s substance abuse policy and an appeal hearing that was scheduled for last Thursday was postponed.
Miller is also facing further discipline following his recent arrest for failing to appear in court for an outstanding warrant.
Miller was at a gun club in Araphoe County (Colo.) at the time of the arrest. He was booked and released Aug. 11, which was an off day for the team.
The 24-year-old Miller had failed to show up for a scheduled court date in January after he was charged in October with careless driving, driving without a license and having no proof of insurance.
NFL Players’ Association assistant executive director George Atallah has said the suspension is not for a violation of the league’s PED policy.
In their first six games of the season, the Broncos face the Super Bowl champion Baltimore Ravens, New York Giants, Oakland Raiders, Philadelphia Eagles, Dallas Cowboys and Jacksonville Jaguars.
The Broncos led the league with 52 sacks last season but lost linebacker Elvis Dumervil to the Ravens. Dumervil and Miller combined for 29.5 sacks, with 18.5 coming from Miller.
