ARLINGTON, Texas -- IndyCar officials had to throw a red flag to slow the cars as they were pulling out of the pit area during Saturday's practice when three workers were spotted on the hot track.
No one was injured.
Practice for the inaugural Grand Prix of Arlington resumed after a delay of several minutes as IndyCar officials checked the temporary 2.73-mile, 14-turn circuit on the streets around the stadiums of the Dallas Cowboys and Texas Rangers.
The television broadcast showed the trio of workers who appeared to be part of a catering crew. One of them was pushing a catering cart in a spot between AT&T Stadium, the Cowboys' home, and a nearby hospitality area.
Cars practicing for Sunday's race hadn't yet gotten up to speed when the track breach was spotted.
