Chiefs coach Andy Reid is holding something special back for the Las Vegas Raiders on Black Friday.Reid said Friday he won’t put running back Isiah Pacheco on the field at Carolina on Sunday, when the Chiefs visit the Panthers for a Week 12 matchup, to give him more time to recover from a broken fibula. Because of the short week of preparation before Friday’s game with the Las Vegas Raiders, Reid opted not to activate Pacheco and defensive end Charles Omenihu to face the Panthers.Reid said Thursday that the Chiefs, including input from trainers and offensive coaches, were already considering protecting Pacheco by taking the decision out of his hands this week.”He’s a spark plug now, emotionally,” Reid said. “He’s something that way, and he’s worked his tail off to get to the point that he’s at now. We’ve got to keep an eye on him that way. He would have played three weeks ago if he had his choice, but that’s sometimes how it goes. I appreciate that mentality. That’s what’s helped him get to this point.”Pacheco and Omenihu practiced the entire week.With three more light practice days before the weeknight game, both players could return for the division clash on Friday.
