Any hope that the Kansas City Chiefs might get Jamaal Charles back in time for the playoffs can now put to rest. Charles reportedly underwend another knee surgery on Monday, his second since the start of Novemeber. Remember, Charles himself was placed on injured reserve earlier this year. The expectation at that time was that he might be able to return. With Charles now clearly lost for the season, Spencer Ware will retain the starting job. He's put up nearly 900 total yards in eight games this season.
