Carlos Huertas has been ruled out of competition for the remainder of the Indianapolis 500 and will have to undergo further evaluation before returning to Verizon IndyCar Series competition. 

An inner ear condition, according to Dr. Terry Trammel, is the reason the 23-year-old Colombian will not race in the 99th Running. 

Huertas qualified the No. 18 Dale Coyne Racing car on the outside of Row 6 but will hand the car over to Tristan Vautier for Carb Day Friday and for the 500 mile race. Vautier qualified for James Davison - and now finds himself as Davison's teammate in the race. 

The No. 18 car will start 32nd based on entrant points, according to Rules 8.1.8.6 and 8.1.8.6.1 of the Verizon IndyCar Series rulebook.
