Jernigan, a second-round draft pick out of Florida State, injured his meniscus during last Thursday's game against the Pittsburgh Steelers. He has not practiced this week and is not expected to play this week against the Cleveland Browns.
During his first two games, he had three tackles. As a team, the Ravens rank 27th in sacks with just two so far this season. Baltimore has allowed 340.5 yards per game during its 1-1 start to the season and ranks 14th in total defense.
The Ravens will play their third AFC North game of the season this Sunday when they face the Browns in Cleveland.
