All-Pro linebacker Von Miller missed the final day of the Denver Broncos' training camp Thursday to address his looming suspension for violating the NFL's drug-abuse policy.
ESPN reported midway through practice, however, that Miller's appeals hearing had been postponed.
NFL spokesman Greg Aiello told The Associated Press that the league was not at liberty to comment on the matter.
Miller has 30 sacks in his first two NFL seasons and a four-game suspension would leave a gaping hole in Denver's defense.
Miller was also arrested Sunday at a firearms shop near the Broncos' practice facility on a warrant for failing to appear in court on Dec. 31 for an October traffic stop in which he was charged with careless driving and not having a license or proof of insurance.
