Veteran defender Jamal Adams was taken to the locker room on a cart with a right knee injury Saturday shortly after his preseason debut with the Minnesota Vikings, who signed him to a one-year contract last month on the eve of training camp.
Adams played 11 defensive snaps before going to the sideline medical tent. His final play was in pass defense on New York Giants quarterback Jaxson Dart's 15-yard touchdown pass to Malachi Fields with 13 minutes, 32 seconds remaining in the second quarter.
"Initial exam does not look good," coach Kevin O'Connell said after the Vikings' 13-10 win. "Don't want to confirm anything until we see the imaging on that."
Adams, 30, was the New York Jets' first-round pick as a safety in 2017. He has made three Pro Bowls but has struggled with injuries in the second half of his career. He played nine or fewer games in the 2022, 2023 and 2024 seasons.
Adams moved to linebacker last season with the Las Vegas Raiders, but the Vikings have been using him at both positions during training camp.
