HOUSTON – IndyCar's return to Houston got off to a bumpy start Friday, literally.
A bump in the concrete in Turn 1 at Reliant Park delayed practice Friday while IndyCar officials erected a chicane of tires that drivers had to navigate their way around when they finally got on the course.
The race promoter was bringing in equipment Friday night to grind down the bump for a more permanent fix. The area typically stores the grass from the Houston Texans field between games.
Qualifying was postponed until Saturday morning for the first face of the doubleheader. IndyCar will hold qualifying for Sunday's race that morning.
Reliant Park is hosting the Houston Grand Prix for the first time since 2007.
