The Chiefs had not listed McCoy on this week's injury report.
McCoy has fallen out of favor with the Chiefs for a variety of reasons. They were concerned early in the season about McCoy understanding his assignments in pass protection. His style of loosely carrying the ball has led to crucial fumbles.
The Chiefs also have a rookie running back, Darwin Thompson, they want to get into the playing rotation. Thompson has played little this season.
McCoy played just six snaps in last week's game.
