The Washington Commanders will be without starting right guard Sam Cosmi for the rest of the playoffs. Cosmi suffered a torn ACL in Washington's NFC divisional-round win over the top-seeded Detroit Lions on Saturday night. An MRI on Sunday confirmed the severity of the injury. The injury occurred about five minutes into the second quarter when Detroit defender Za'Darius Smith inadvertently hit the back of Cosmi's legs, with Cosmi's right leg pinned under Smith's body. Cosmi hobbled off the field with trainers. Cosmi was replaced by veteran backup Trent Scott, who is playing with his fourth team in seven NFL seasons.
