Hamlin out for todays race

Just announced Hamlin out due to Sinus issues affecting his vision.  I have Gordon over Hamlin in a head to head matchup. 

Do you know if the driver has to start the race for the bet to stand?

That didn't take the entire msg for some reason.  I have Gordon over Hamlin already, so will that bet become no action or will it still be based on the car?  NEVER had a driver drop out after a bet was placed, so didn't know the rules on this...

Will become no action

1. The Official Nascar winner of the race will be the winner including all races which are halted prematurely.
2. Later changes made due to appeals or penalties for rules infractions, dangerous driving, or other are not applicable for betting purposes.
3. When wagering on a match up both drivers must start the race.
4. If a driver is replaced during a race, the position the new driver finishes in will be awarded to the original driver for both win odds and in match ups.
5. If a If a race is postponed for any reason from the originally scheduled date and time, wagers on race winner and matchups will be valid till 11:59PM two days later. After that all wagers will be cancelled.
