Cincinnati Bengals defensive end Michael Johnson suffered a knee injury that caused him to leave Thursday's game against the Baltimore Ravens, according to Mike Preston of the Baltimore Sun.
Sam Hubbard replaced him in the lineup, while Jordan Willis could also see extra playing time while the starter is unavailable.
Johnson has been one of the most durable players in the NFL over his career, especially for such a physical position on the defensive line. He only missed four games in his first nine seasons in the league, missing one game last season after suffering a concussion.
