The Panthers have lost Thomas Davis for the year due to a torn right ACL.  Davis played in 7 games for the Panthers this season and he made 61 tackles, 3 tackles for a loss, he defensed 5 passes, had 1.5 sacks and he had 2 interceptions.  Davis will be replaced in the starting lineup by veteran Landon Johnson who was a 4-year starter for the Bengals before signing with the Panthers.  He has played in 8 games this season and he has 7 tackles including 1 tackle for a loss.  Landon Johnson should do a solid job filling in for Davis who has made a stunning transformation into a linebacker as he was a safety when the Panthers drafted him.
