Patriots quarterback Tom Brady was helped off the field midway through the first quarter against the Chiefs. Brady threw a completion to Randy Moss, who ended up fumbling the ball on the play. As he passed, Brady was grabbed on the left knee by a Kansas City defender, causing him to hobble around before receiving help to the sideline. Matt Cassel took over for Brady with a little more than a minute left in the first quarter. The Patriots have listed Brady as questionable to return against Kansas City. New England, who lost six fumbles all of last season, lost two in the first eight minutes against the Chiefs.
