Kansas City, Mo. ? Jamaal Charles practiced in a limited capacity Friday for the second straight day, raising hopes that the Chiefs’ Pro Bowl running back will be available for Sunday’s game in Miami.

Charles sustained a high ankle sprain in last week’s loss to Denver.

“He looked a little sore,” Chiefs coach Andy Reid said, “but he did OK. He worked yesterday (Thursday). He loosened up, kind of went as it went. We’ll just see how he does.”

Charles did not practice Wednesday, and it was feared that the injury could keep him out of the lineup for several weeks.

But he told Reid that he wanted to try practicing Thursday, and he wound up splitting time with the first-team offense and the scout team.

He remains listed as questionable. If Charles is limited or unable to play, the bulk of the carries would go to second-year pro Knile Davis, who played well last week.

The 5-foot-10, 227-pound Davis ran for 79 yards and two touchdowns against Denver.

“He’s a guy as we saw last week in the football game when two-five went down,” Chiefs offensive coordinator Doug Pederson said, “came in and had an outstanding game. He’s understanding his role, and that’s a big part of what he does.”

Safety Eric Berry (ankle) and WR/RB De’Anthony Thomas (hamstring) have been ruled out for the Miami game. Reid doesn’t believe Berry’s injury is related to the right heel tendinitis that caused him to miss preseason games. “I think they’re separate deals,” Reid said.
