What happened to St. Arnaud

Anybody know why Severance was put back in for round two?

 

"Really great track conditions for round two.St. Arnaud's car failed fuel check, so Severance is reinstated."

Thanks, I see that now. Was watching the live stream from the track and they said nothing about it.
