"When officers approached, they found the driver, later identified as Paul Pierce, asleep at the wheel," California's highway patrol told Dennis Broad and Jonathan Lloyd of KNBC-TV in a statement. "Officers noted signs of alcohol impairment and conducted a DUI investigation."

Per Broad and Lloyd, Pierce has since been released.

Pierce is from California, having been born in Oakland and educated at Inglewood High School. He played for the Clippers from 2016 to '17, though he is best known for his 15-year tenure with the Celtics.
