Chiefs running back Jamaal Charles was injured on Friday night against the Eagles. Charles took a short pass from Matt Cassel and was just going out of bounds when Philadelphia's Nate Allen pushed him out with a hit around the ankles. He seemed to be holding his right arm but it was not immediately clear where Charles was hurt. He rushed for 1,120 yards last season. ESPN Insider Adam Schefter reported on Saturday that Charles simply hit his funny bone and is suffering from no injury at all.
