CHARLOTTE, N.C.-- Carolina Panthers linebacker Jon Beason will miss the rest of the season with a torn left Achilles tendon.
The team announced on Monday the results of an MRI exam that revealed the tear Beason sustained in a 28-21 loss at Arizona in the season opener Sunday.
He was carted off the field in the second half.
Beason signed a $51 million, six-year deal this summer, including a $20 million signing bonus.
A first-round pick in 2007, he has played inside and outside linebacker for the Panthers and is one of their defensive leaders.
