Kansas City Chiefs RB Jamaal Charles (knee) recently returned to practice after knee surgery, but he has yet to play in a preseason game. He is unlikely to play Thursday, Sept. 1, in the exhibition finale. He is considered behind schedule, and while there hasn’t been a setback, he isn’t confirmed as the full-time featured back, either. RB Spencer Ware has taken first-team reps for training camp and the preseason, with RB Charcandrick West also seeing first-team reps. ‘For Jamaal, it’s (a matter of) getting trust in the leg,’ head coach Andy Reid said Tuesday, Aug. 30. ‘Every day he does a little bit more and a little bit more and his cuts are a little bit sharper. It’s just a matter of time and we’re OK there. We’re OK with that.’
