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 on Thursday, and he wound up splitting time with the first-team offense and the scout team.He remains listed as questionable.
