The Detroit Lions lost two of their defensive starters — and biggest free agent additions — potentially for the rest of the season.
The Lions placed defensive tackle Danny Shelton (knee) and cornerback Desmond Trufant (hamstring) on injured reserve Wednesday.
Both were injured in last week's loss to the Houston Texans, and both must now miss a minimum of three games.
The Lions (4-7) have just five games remaining, including Sunday against the Chicago Bears.
Shelton and Trufant were two of the Lions' most significant signings this offseason, though neither has had the defensive impact the Lions hoped.
