Deshaun Watson hit Artavis Scottwith 10-yard touchdown pass in overtime and Marcus Edmond finished it with an interception in the end zone as No. 3 Clemson beat North Carolina State 24-17 on Saturday.
The Tigers (7-0, 4-0 Atlantic Coast Conference) looked all but done in regulation, but Kyle Bambard's 33-yard field goal try as time experience was wide right.
Clemson took full advantage with Watson's strike to Scott. Then Edmond reached high to grab a long throw down the middle from NC State's Ryan Finley and Clemson had escaped with its path to the ACC title game and the College Football Playoffs still all clear.
It wasn't the prettiest game for Clemson, which gave up 397 yards and turned it over four times - including Watson's first-ever pick six - to the Wolfpack (4-2, 1-1).
Clemson took a big hit early on when running back Wayne Gallman came out, looking woozy and out of it as he headed to the locker room. Gallman, the team's leading rusher, did not return.
Receiver Hunter Renfrow, who had six catches in his first game since Sept. 10 because of a broken hand, was hurt in the fourth quarter and came out the rest of the way.
North Carolina State: The Wolfpack look like a team on the rise, one of the few the past two season that has been able to take the Tigers down to the wire.
Clemson: The Tigers probably won't gain much support in the rankings with its tight victory at home. But in the end, it might not matter if they are standing on top of the league with a perfect record.
North Carolina State: The Wolfpack head to No. 7 Louisville where they are 0-3 all time, including a 30-18 defeat two years ago.
Clemson: The Tigers get the week off before traveling to No. 14 Florida State on Oct. 29. Clemson has won just once (2006) in its past 12 visits to Tallahassee.
