The first practice in the Las Vegas Grand Prix was called off after just
nine minutes when a manhole cover seriously damaged a formula one driver's car,
Carlos Sainz of Spain drove over a water main cover that badly damaged his Ferrari
causing organizers to call for a stop to the practice
until the entire track could be examined and repaired.
The second practice session was delayed until 2:30 a.m. local time
and it was extended to 90 minutes.
The Las Vegas Grand Prix takes place Saturday night.
