Panthers Fear Beason Out For Year

This would be a major blow to the team as we would be losing our defensive leader.  All I can say is thank God we kept Dan Connor and re-signed James Anderson and Thomas Davis.  This news puts a big damper on the amazing performance by Cam.  Hopefully the fears are just that and not reality.   Fingers crossed.

As the reports on Beason roll in, his injury appears as serious as initially believed. According to the Charlotte Observer, Panthers coach Ron Rivera called the injury “dire” and said Beason will have an MRI exam Monday. A source tells the Gaston Gazette that the injury is “very significant.”
