The league announced the suspension on Tuesday, but said only that the seven-year veteran had tested positive for a banned performance-enhancing substance, but didn’t go into specifics because of the confidentiality of the testing program.
Adderall is prescribed to patients with Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder. It increases concentration for those with ADD/HD, and provides a boost in energy for those without ADD/HD.
Ten other known players have been suspended for the use of Adderall this season.
Griffin will miss the final four games of the regular season without pay.
The cornerback wasn’t present for the early portion of Nov. 28th’s practice and Coach Mike Shanahan said only that Griffin was tending to “some personal business.” It’s not clear if that absence was related to the suspension or appeals process.
The league, however, doesn’t announce suspensions until after the appeals process has been played out.
