All bar two of the 14 Daytona spectators hospitalised after Saturday's NASCAR Nationwide Series race incident have now been released.
The remaining two are still in a stable condition at Halifax Health.
The injuries were sustained when Kyle Larson's Chevrolet flew into the debris fence in a last-lap pile-up on Saturday.
His car's engine went through the fence while a wheel landed in the grandstand.
Two of the injured were in a critical condition at first, with one sustaining life-threatening injuries.
But both were upgraded to 'stable' status by Sunday morning.
A further 14 people were treated on site at the Daytona medical centre.
