The NFL notified the Bengals that linebacker Darryl Blackstock will be suspended for the next four games, for violating league policy on performance-enhancing substances.
Blackstock, a fourth-year NFL player, has played in Games 1-5, with three tackles on defense and one on special teams. He will not be allowed to attend meetings, practice or play for the period of Games 6-9. He will be eligible to return to team activities on Nov. 10, the Monday before Game 10 on Nov. 16 vs. Philadelphia.
"I've apologized to my coaches and teammates for an unfortunate mistake," Blackstock said. "I did not intentionally violate the policy, but I know it's my responsibility to use only approved nutritional supplements, and I didn't realize I was taking an over-the-counter product that included a banned substance. I also want to apologize to our fans, and I'll do everything I can to be ready to come back strong next month."
