McKinnon (groin) won't play Sunday against the Raiders, Matt McMullen of the Chiefs' official site reports.
With McKinnon sidelined Week 12, Clyde Edwards-Helaire will likely step in as the top backup to starting running back Isiah Pacheco, while La'Mical Perine and Deneric Prince are candidates to be elevated from the practice squad to add depth to the backfield. McKinnon will target a potential return to action Dec. 3 against the Packers.
