Kansas City Chiefs star running back Jamaal Charles was carted off the field this morning, according to the Kansas City Star.

However, Kansas City Chiefs coach Andy Reid emphasized that the injury isn't serious.

Reid told Kansas City reporters that it's just a strained foot and that X-rays were negative.

Meanwhile, rookie offensive tackle Eric Fisher, the top overall pick of the draft, is back at practice despite thumb and shoulder injuries.
