Race leader Michael McDowell retired after second serious accident in Daytona

The second major accident Saturday night occurred eight laps from the end of the Coke Zero Sugar 400 NASCAR Cup Series race at Daytona International Speedway.

A total of 14 vehicles were involved in the accident on lap 152.

Race leader Michael McDowell spun, slid across the field and was hit by Joey Logano on the inside lane, sending McDowell's No. 34 Mustang flying.

For some reason, McDowell did not roll over and the car landed upright, but was out of the race.
