The Bears may face the Redskins Sunday at Soldier Field without a key member of their defense.
Outside linebacker Pernell McPhee, who is tied for the team lead with five sacks, did not practice Friday due to a knee injury and is listed as doubtful, meaning there's only a 25 percent chance he'll play.
McPhee has been bothered by the injury for more than a month. He sat out a win over the Rams Nov.
