CHAPEL HILL, N.C. -- Mitch Trubisky came off the bench and threw four second-half touchdown passes to help North Carolina beat Delaware 41-14 on Saturday.
Trubisky completed 17 of 20 passes for 312 yards, all career-high marks. He also added 39 rushing yards on six attempts.
Mack Hollins caught touchdown passes of 33 and 64 yards for the Tar Heels (3-1), who closed the nonconference portion of their schedule with three consecutive wins.
Trubisky took over for starting quarterback Marquise Williams on North Carolina's final possession of the first half and played the rest of the game.
Williams, who was sacked for an 11-yard loss on his final play, spent the second half on the sideline. He walked gingerly but showed no other sign of injury as he conversed with teammates and coaches during the final two quarters.
Thomas Jefferson rushed for 163 yards and two touchdowns for the Blue Hens (1-3).
Trubisky threw touchdown passes on four consecutive possessions over a 19-minute span to help the Tar Heels turn a close game into a rout.
He started the barrage with two deep scoring passes to Hollins over the top of Delaware's defense. Trubisky hit Bug Howard with a 10-yard strike early in the fourth quarter and then found Ryan Switzer for a 63-yard score on a nifty catch and run.
The Tar Heels racked up 568 total yards and finished a game without punting for the first time since 1996.
The Blue Hens hung tough despite playing without leading rusher Jalen Randolph and leading receiver Diante Cherry, who sat out with injuries.
Jefferson silenced the sparse, rain-soaked crowd on the second play by ripping off a 72-yard touchdown run. He broke a tackle in the backfield and then streaked untouched to the end zone for the longest run by a freshman in program history.
The Tar Heels tied the game with an 18-yard touchdown run by Williams on their first possession, but their high-powered offense was stuck in the mud in soggy conditions for much of the first half.
Nick Weiler converted field-goal attempts of 46 and 26 yards to give North Carolina a 13-7 lead at halftime.
The Blue Hens kept the game close for almost three quarters despite featuring a one-dimensional offense. They finished with 279 rushing yards, but quarterback Joe Walker completed 4 of 10 passes for just 24 yards.
