"An MRI revealed that he will need to have a minor knee procedure and that has been scheduled," Marrone said in the statement. "He will miss the remainder of the preseason and then be re-evaluated at that time. Kevin Kolb will be our starting quarterback for this weekend's game at (the Washington Redskins)."
The first-round draft pick calmly guided Buffalo's fast-paced offense and showed an ability to get rid of the ball quickly while making smart decisions. Kolb, meanwhile, averaged just over 5 yards per throw and suffered an interception on a tipped pass. Boos rained down inside Ralph Wilson Stadium as Kolb struggled to move the team.
One day later, Buffalo is mired in a tricky situation.
UPDATE: Marrone told reporters Sunday that Manuel underwent his knee procedure that morning in Buffalo.
