EAGAN, Minn. (AP) — Minnesota Vikings cornerback Holton Hill has been suspended for an additional four games, this time for violation 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. The NFL announced this punishment on Tuesday, three days before the full squad takes the field for the first time at training camp.

Hill, who had a promising rookie year with extensive playing time while starters Xavier Rhodes and Trae Waynes were injured, started three games in 2018. He went undrafted out of Texas after a positive test for marijuana, according to an NFL Network report last year.

Hill can participate in preseason games and practices, but he won’t be allowed to return to the active roster until Oct. 25. Hill is the second Vikings player this month to receive a suspension for substances of abuse. Running back Roc Thomas got a four-game ban last week and was subsequently waived.
