Minnesota Vikings cornerback Holton Hill has been suspended for an additional four games, this time for violation of the NFL’s policy and program on substances of abuse.

Hill will be out of action for the first half of the season, having previously received a four-game ban the league handed him in April for violation of the policy on performance-enhancing drugs.

Hill can participate in preseason games and practices, but he won’t be allowed to return to the active roster until Oct. 25.
