Jason La Canfora of the NFL Network says that a league source has indicated the Panthers have been in contact with DT Alfonso Boone. He was with the Chicago Bears from 2000 thru 2006, then spent 2 years with the Kansas City Chiefs. He was released on Tuesday. Alfonso is 33 years old, 6'3", and 305 lbs. with 9 years of experience in the NFL. In 113 games, he has posted 150 tackles, 12.5 sacks, and 13 passes defensed. According to some, Boone was ill-suited for the Chiefs new 3-4 scheme and became expendable.
