Jamaal Charles was forced from Saturday's Wild Card game with a possible concussion, and is questionable to return. Looking to avoid a big hit on the Chiefs' opening drive, Charles went to the ground in awkward fashion, appearing to slam his head on the turf. He remained down for several moments before walking to the sideline under his own power. He attempted to get loose before being escorted to the locker room. It's quite possible he's concussed. Kansas City finished off the drive with a score, but losing Charles would be hard to overcome. We should receive official word before halftime.
