KANSAS CITY, Mo. (AP) — Vikings star Adrian Peterson offered encouragement to Jamaal Charles on Wednesday, three days after his Chiefs counterpart sustained a torn ACL in his right knee against Chicago. It was Charles who, after tearing his left ACL four years ago, reached out to Peterson later in the season. Minnesota’s running back had just torn the same ligament in his knee that December. Both players returned from their injuries the following season.

Peterson said he can’t imagine having to go through the painful hours of rehabilitation for a second torn ACL, which Charles is facing. But he also said that his fellow Texan has the “God-given ability” to come back from such a devastating injury. The Chiefs visit the Vikings on Sunday.
