According to several sources, Von Miller, Denver Bronco's Pro Bowl linebacker, was facing a suspension for four games.  Miller was accused of violating NFL's substance-abuse rule.

The case was still in its appeals process hence, it was unclear if the suspension would ultimately stand.  However, a league source stated that Miller's appeal was not set yet.

George Atallah, the spokesperson for NFL Players Association, made a statement through Twitter. He said that the union was working closely on the appeal made by Miller. "I can also confirm that Von's case does not involve the Steroids and Related Substances Policy," he added.

On Monday, the Denver Post publicized that Miller tested positive for amphetamines and steroids. The Denver Post reported that Miller used the substances in 2011 during his rookie season.

Miller's net worth was US$20 million. This year, his salary reached up to US$7 million. His 4-year contract with Denver Broncos was worth US$21 million. This included a US$13 million worth bonus.
