For Player Touchdown Scorer markets, the bet stands if the player was listed as active, even if they didn’t play a snap.
For other player-based markets (passing yards, rushing yards, fantasy points), the player must play at least one snap, or bets are void.
Example: If you bet on a wide receiver to score a touchdown and he is active but doesn’t take the field, your bet still stands. But if your bet was on him to gain 50 receiving yards, and he doesn’t play, the bet is void.
