CHARLOTTE, N.C. -- The Carolina Panthers have lost another linebacker to a season-ending knee injury.
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.
