CHARLOTTE, N.C. -- The Carolina Panthers have lost another linebacker to a season-ending knee injury.
The Panthers placed Landon Johnson on injured reserve Tuesday and signed linebacker Jordan Senn. Johnson hurt his medial collateral ligament during Thursday's loss to the Miami Dolphins in his second start at weakside linebacker after Thomas Davis was lost for the season.
Senn adds depth at linebacker but also provides a needed body on special teams. He played with the Indianapolis Colts as an undrafted rookie in 2008 and was released before the start of this season. Senn was later re-signed and played in two games before being released again.
Johnson had 12 tackles in the past two games.
