Panthers running back Christian McCaffrey tested positive for COVID-19, according to NFL Network's Ian Rapoport.
Carolina announced on Nov. 29 that McCaffrey would miss the remainder of the '21 season due to an ankle injury. He was placed on the team's injured reserve list.
McCaffrey suffered the ankle injury during the first half of the Panthers' 33–10 loss to the Dolphins. He played one snap in the second half of that game.
The 25-year-old played in Carolina's first three games of the season before missing five games due to a hamstring injury.
