Following a torn ACL and potentially more suffered in Sunday's win against the Pittsburgh Steelers, safety Tony Jefferson was placed on injured reserve on Monday, the team announced.

In a corresponding move, Baltimore brought up wide receiver Sean Modster from the practice squad. 

Jefferson, a seven-year veteran who was in the midst of his fourth season in Baltimore is just the latest member of the secondary to go down in 2019. With Tavon Young also out for the season and Jimmy Smith missing some time, a struggling back part of the defense continues to get thinner.

As for Modster, the undrafted free agent from Boise State, the rookie receiver will get a chance to make an impact on the roster. In his senior season of college, he racked up 68 receptions for 978 yards and eight touchdowns.
