If the ball is fumbled backwards and is recovered by the team that fumbled, the ball is spotted at the spot. If it is fumbled forward and recovered by the team that fumbled, the ball is spotted at the point where the ball was intially fumbled, it cannot be advanced, unless the player that actually fumbled recovers it. This all applies within the last 2 minutes of the 1st half and within the last 2 minutes of the game.
