The Panthers have lost 27-year old starting linebacker Thomas Davis for the year after he re-tore his right ACL in OTAs.  It was the second time in only seven months that Davis has torn his right ACL.  He played in 7 games for the Panthers last season and he had 61 tackles, defensed 5 passes, had 1.5 sacks and he had 2 interceptions.  In his five years with the Panthers, Davis has played in 69 games in which he has 390 tackles, 22 passes defensed, 11 sacks, 8 forced fumbles and 3 interceptions.  This is a big blow to the Panthers who were counting on a healthy Davis to boost the defense.
