The Baltimore Ravens ruled quarterback Lamar Jackson out for the remainder of Sunday's game against the Denver Broncos with the knee injury he suffered in the first half.
While Jackson was wearing a protective sleeve on his right arm ahead of a Week 3 game against the New England Patriots that he ultimately played in and missed five games last season, he has been fairly durable for much of his career given his playing style as a quarterback who uses his arm and legs.
The Louisville product played at least 15 games in each of his first three seasons in the league.
