Kansas City Chiefs running back Jamaal Charles was lost for the season when he tore his ACL in Week 5 against the Chicago Bears, but the Pro Bowler is trying a unique approach to his recovery.
According to Jenny Vrentas of the MMQB, the 28-year-old veteran recently underwent stem-cell treatment—largely out of curiosity:
I just had a small procedure done on the knee a few days ago, but I have been back at the facility rehabbing with the trainers and some of my teammates who are also on injured reserve.
