KANSAS CITY, Mo. (AP) — Chiefs running back Jamaal Charles was on the practice field for the start of a three-day minicamp, though All-Pro safety Eric Berry was absent as his representatives negotiate a long-term contract. Charles has been ahead of schedule after having surgery last season to repair a torn ACL in his right knee. He has been involved in some of the voluntary workouts prior to Tuesday, and has insisted all along that he intends to be ready by the start of training camp.

Charles was hurt in a Week 5 game against the Bears. Berry has been absent all offseason after getting the franchise tag, which would pay him about $10.8 million next season. Since he has not signed the franchise tender, he is not under contract and obligated to attend the mandatory minicamp.
