Tennessee women's basketball head coach emeritus Pat Summitt and NASCAR driver Trevor Bayne stand in front of a "We Back Pat" race car on Friday in Thompson-Boling Arena. Bayne, a Knoxville native and 2011 Daytona 500 champion, will drive a similar car in the Nationwide Series Food City 250 at Bristol Motor Speedway on Aug. 24 to help raise money for the Pat Summitt Foundation, which helps raise money for Alzheimer's research. Summitt announced last August that she had been diagnosed with early-onset dementia, Alzheimer's type, and stepped down as the Lady Volunteers head coach in April. She won an NCAA-record 1,098 games during 38 years at the helm. She will also serve as the grand marshal for the race.
