Running back Jamaal Charles did not practice Wednesday and the Chiefs, who must win their remaining three games to reach the playoffs, might take on Oakland without their Pro Bowl featured back.

If Charles is not cleared to return with an ankle injury that briefly took him out of last week’s game, Knile Davis will start, coach Andy Reid said.

“We’ve done it before,” quarterback Alex Smith said of playing without Charles. “Obviously Jamaal leads the NFL in scoring. He’s an elite, elite player in this league. But you’ve got to find a way. Next man up, we’ve got to go.”

Davis has 427 rushing yards and five touchdowns in 2014. He also has 14 receptions.

Tight end Travis Kelce said the Chiefs would definitely alter the plan of attack without Charles.

“Jamaal is a great player,” Kelce said. “I said it once: he is the best in the league at what he does. It will change the gameplan a little bit but at the same time, we’re a team. We have to go on and play with whoever is out there on the field.”
