At the NHRA Arizona Nationals on Sunday, John Force won his second-round race before an engine explosion sent his Funny Car careening into racer Jonnie Lindberg.
The two cars tangled up by parachutes, hit one wall, then the other before coming to a stop in a cloud of smoke. As a precaution, the 68-year-old veteran was transported for further evaluation and released Sunday evening from Chandler (Ariz.) Regional Hospital.
