Chicago Bears linebacker Roquan Smith left Thursday's game against the Dallas Cowboys with a pectoral injury suffered on the game's first drive and was ruled out for the rest of the contest.
Smith was injured after making contact with Cowboys running back Ezekiel Elliott as he crossed the goal line to cap Dallas' opening 17-play, 75-yard touchdown drive. Kevin Pierre-Louis replaced Smith on defense.
Chicago's 1st-round pick in 2018 (eighth overall), Smith had a career-best 15 total tackles last week. The Bears are already without another starting inside linebacker, Danny Trevathan (elbow), who was replaced in the starting lineup by Nick Kwiatkoski.
