CHAPEL HILL - Trailing by 13 points after a mistake-filled first half, Chapel Hill ground out two third-quarter touchdowns on a 6-yard run by Darius Allen and 9 yards by Alex Colson to defeat Northern Vance 20-19 in a Carolina 3A Conference game Friday night.

Allen, who also scored on a 6-yard run in the first quarter, finished with 130 yards and two scores on 21 carries to help Chapel Hill improve to 6-2, overall, 1-1 Carolina 3A.

Northern Vance, falling to CHHS for the fourth straight year, dropped to 1-6, 0-2. Carolina 3A.

Sophomore Tyrick Bullock returned a kickoff 85 yards for one touchdown and scored another on the last play of the first half to spark Northern Vance to a 19-6 halftime lead.

Three plays after Chapel Hill left a high punt snap back at its own 5-yard line, quarterback Tyquan Bryant scored Northern Vance’s first touchdown on a 5-yard keeper around left end just 8 seconds into the second quarter.

Chapel Hill answered with a 9-play, 55-yard drive to tie the game at 6-6 on Allen’s first 6-yard TD off tackle with 3:38 left in the half. Bullock stunned the crowd at Culton-Peerman with his 85-yard return of the ensuing kickoff for a 13-6 Northern Vance lead.

Chapel Hill again gave the Vikings great field position by running into punt returner receiver Micheal Spinner at midfield. Northern Vance moved 35 yards in 1:51 to score on Bullock’s 1-yard dive as the second quarter expired, taking a 19-6 lead.

“We really stunk it up in the first half,” Chapel Hill quarterback T.J. Johnson said. “The coaches let us know they weren’t happy with us at halftime.”

Chapel Hill took the first possession of the second half and drove 75 yards in 12 plays and capped it with Allen’s second 6-yard touchdown run, jamming in behind the "jumbo package" of lead blocking backs Alex Colson and Brian James.

After the Tigers held Northern Vance to a three-and-out on the next possession, Chapel Hill’s Alex Duncan blocked the punt and gave CHHS the ball at the Vikings’ 34.

Five plays later, all rushing, Colson powered in the ball himself for a touchdown and then again led Allen into the end zone for a two-point conversion and a 20-19 lead with 2:31 left in the third quarter.

Chapel Hill held the Vikings to 19 total yards in the fourth quarter to complete the second-half shutout.

“Holding them scoreless in the second half was good,” Chapel Hill coach Issac Marsh said. “Otherwise, I wasn’t very happy with our play.”
