San Diego Chargers inside linebacker Jonas Mouton was declared out or the season by coach Mike McCoy tonight.
Mouton tore the anterior cruciate ligament in his right knee during a Thursday practice.
Although Mouton is a former second-round draft pick from Michigan, he's still a backup.
And he missed nearly the majority of his rookie season with a shoulder injury.
This injury thins depth at inside lineabacker, which features rookie starter and former Notre Dame star Manti Te'o.
