The UIL made a ruling on it a couple years ago when Throckmorton did it. In the case of a district forfeit, a team is allowed to schedule another opponent, they still get credit for the district forfeit win and they also get credit (or detriment) for the game that they actually play. So in that one case, they can actually be 11-0 after having played 10 games. You CAN get credit for both in the same week, if and only if, it is a DISTRICT forfeit.
