Kansas City Chiefs running back Jamaal Charles is listed as doubtful with a knee injury for his team's game against the New York Jets this Sunday.
Charles has been inactive for the Chiefs' first two games, while he recovers from a torn ACL suffered last September.
Spencer Ware is expected to continue filling in as the starting running back, with Charcandrick West helping out in spot duty.
While Charles' designation indicates he will likely miss Sunday, head coach Andy Reid suggested Friday morning that Charles could dress.
