INDIANAPOLIS (AP) _ A.J. Foyt Jr. was rushed to the hospital with stomach pain during Friday's opening practice for the United States Grand Prix.

Foyt, a four-time Indy 500 winner who was at Indianapolis Motor Speedway as a spectator, was checked at the hospital, released, and returned to the track.

Foyt, 65, had an angioplasty procedure on Sept. 11, to clear blockage from the arteries near his heart.
