Yes, in the NFL, negative rushing yards are subtracted from a running back's total rushing yards. If a running back loses yards on a carry, those negative yards are counted against their overall rushing total for that game and season. This means that a player's rushing yards reflect both positive and negative yardage from their carries.
In the NFL the stat of all purpose yards usually refers to the yards obtained during a game, season, or career by a running back or a receiver. The yards referred to are both gained by receiving and rushing. Normally a running back will have the most all purpose yards, because receivers do not usually run the ball as often as runners catch the ball. Due to the formations in the NFL this can be achieved.
