Police say Blair was driving 117 mph across the Fort Pitt Bridge, according to the Pittsburgh Tribune-Review. Citing charging documents, the newspaper reported that the arresting officer smelled "a strong odor of marijuana emitting" from Blair and took him to UPMC Mercy hospital for blood tests, which indicated a positive result for cannabinoids, according to the criminal complaint.
Blair, 20, was charged with DUI, speeding, careless and reckless driving, and failure to wear a seatbelt.
Panthers coach Pat Narduzzi told local reporters at the ACC Kickoff that Blair told him about the incident immediately after it happened, saying that Blair faced some punishment and that "there will probably be more."
Blair, a sophomore who overcame a stroke in high school, led Pitt with 5.5 sacks last season.
