Charity sentence
The loser donates blood, with the appointment booked by the league and the post-donation cookie photo as proof. One league names its consolation bracket the Blood Bowl accordingly. The rare punishment that saves up to three lives while still being a punishment.
Budget note: this one costs nothing but dignity, which makes it a strong pick for leagues that would rather spend the pot on the champion than on the loser's downfall.
