Chris Blewitt made a 48-yard field goal with six seconds left as Pittsburgh stunned No. 2 Clemson, 43-42, spoiling a record-setting Saturday for quarterback Deshaun Watson and complicating the Tigers' path back to the College Football Playoff.
It was the biggest win for the Panthers (6-4, 3-3 Atlantic Coast Conference) since knocking off No. 2 West Virginia, 13-9, in 2007.
Watson threw for an ACC record 580 yards and three touchdowns for Clemson (9-1, 6-1). But his third interception gave Pitt the chance to crawl back from a 42-34 deficit. After Saleem Brightwell's pick and 70-yard return, James Conner finished the drive with a 20-yard TD run.
