Dolphins tailback Daniel Thomas suffered a right knee injury and sat out the second half of Sunday's game against Jacksonville. Thomas, who carried the ball once, gaining six yards against the Jaguars, could be lost for the season because of the injury. His absence forced the Dolphins to finish Sunday's game with Reggie Bush and Lamar Miller as the only tailbacks, and not having him limited the Dolphins' goal line playcalling. Thomas has carried the ball 91 times for 325 yards and scored four rushing touchdowns this season. Source: Sun Sentinel
