2025 FCS Playoffs Going back to the Connors brothers' medical waiver:
"To get an NCAA medical hardship waiver, an athlete must suffer a season-ending injury or illness, not compete in more than 30% of the season's games (or 33% for Division III), and the injury must occur before the midpoint of the season."
If UC Davis loses against North Dakota state, then I think that would be 4 games out of 13, or 30.8%.
