Marcell Dareus Facing Four Game Suspension for Violating Substance Abuse Policy

Former Tide defensive lineman Marcell Dareus has been suspended for four games by the Buffalo Bills for violating the NFL's substance abuse policy.

The Buffalo Bills organization released a statement informing the public of Dareus' suspension, and according to Ian Rapoport of NFL.com, this suspension is in reaction to either a failed or missed drug test.

This will be the second suspension that Dareus has faced since being drafted in 2011, his first coming at the beginning of last season, as he served a one-game suspension due to being arrested for possession of a controlled substance and possession of drug paraphernalia.

Dareus posted an apology on his Instagram account on Tuesday saying, "With deepest regrets I want to apologize to the @BuffaloBills organization, my fans, my family and the entire NFL football community for the incident that led to me missing 4 games for the upcoming 2016-2017 season... Thank you for continuing to support me - I will rise above this setback, as with every challenge brings an opportunity for growth."

The Buffalo Bills kickoff the NFL regular season on September 11 against the Baltimore Ravens in Baltimore, MD.
