Von Miller is practicing with the Denver Broncos as a new report suggests the All-Pro linebacker could be facing an even longer suspension than originally thought.

ESPN, citing people it didn't identify, reported that Miller might have to sit out at least six games for violating the league's drug-abuse policy. In that case, Miller's earliest possible game would be Oct. 20 at Indianapolis.

Previously, it was believed Miller was facing a possible monthlong suspension to start the 2013 season. Miller had repeatedly expressed confidence he was going to successfully win an appeal of that penalty, insisting he had "done nothing wrong."
