SPRINGDALE — Two weeks ago, Northside's playoff hopes appeared to be on life support.

Now, the Grizzlies are heading to the 7A quarterfinals.

Northside scored two touchdowns in the second half to rally from a 9-7 halftime deficit and the Grizzlies' defense turned in another strong performance as Northside knocked off Springdale Har-Ber, 21-9, in the opening round of the 7A playoffs on Friday.

With the win, Northside's first postseason win since 2014, the Grizzlies (4-7) will head to the quarterfinals next week and a trip to face 7A-Central champion and undefeated North Little Rock.

"I'm so excited; they played a great game last week (against Southside) and we came back this week and did it again and we're just tickled to death. ... We're young and we're improving, that's what we want," Northside coach Mike Falleur said. "We're going to go home and enjoy this this weekend and see if we can't go to (North) Little Rock and get another one. ... We just told them to keep playing hard and don't get beat deep."

Northside junior quarterback Deuce Wise completed 10-of-17 passes for 112 yards and two touchdowns, both going to senior receiver Jordan Dilworth. The latter was from 3 yards out on a third-and-goal play with 7:48 left, which gave Northside its two-score advantage.

"It feels great, coming out here and proving everybody wrong. ... We passed really well, our running game was working," Wise said. "We were clicking on all cylinders and it's just a great feeling."

The Grizzlies' defense, which held Southside to 13 points last week, gave up 194 total yards in Friday's win, with 68 of those coming in the second half. Northside also registered six quarterback sacks, with the final one coming from junior lineman Raytel Rone on a fourth down with 2:49 remaining.

With Har-Ber (7-4) down to just one time out, the Grizzlies were able to run out the rest of the clock. Tailback Eli Bolton converted a third-down run for 7 yards down to the Har-Ber 4, which prompted the Grizzlies to utilize the victory formation.

Northside came out of the locker room to start the second half and proceeded to put together a solid drive, which went to the Har-Ber 25. But the Grizzlies fumbled the ball back to Har-Ber.

When Northside got the ball again following a punt on the ensuing series, the Grizzlies finished things off, with a little trickery mixed in.

Facing a third-and-9 at their own 48, Wise threw a short route to receiver J.T. Thorne. Thorne then launched a deep pass, which was caught by tight end James Clayton for a 33-yard gain down to the Har-Ber 19.

Wise scampered 10 yards to the 9, where on the next play, sophomore tailback Jackson King took a pitch around the right side and darted in for the touchdown midway into the third quarter. Jose Paredes added the PAT to give Northside a 14-9 advantage.

On the final play of the third quarter, Northside punter Jason Serpas pinned Har-Ber deep with a 37-yard kick down to the Har-Ber 5. The Grizzlies' defense forced a three-and-out, setting up another punt, which set up great field position for Northside at the Har-Ber 41.

Five plays later, the Grizzlies built their lead. Moments after Wise connected with Clayton for a 29-yard pass to the Har-Ber 5, Wise rolled to his right on third-and-goal and found Dilworth in the end zone for the TD.

Dilworth caught seven passes for 71 yards and two TDs. His first TD began the scoring early in the second quarter, as he caught a low throw from Wise and went down the left sideline for a 21-yard score, and Paredes kicked the PAT to give Northside a 7-0 lead. Dilworth's TD capped a five-play, 38-yard drive.

Har-Ber answered eight plays later, tying the score at 7-all. Late in the first half, a bad snap on a Grizzly punt attempt sailed out of the end zone for a safety, putting Har-Ber up by two points.

Wise was the Grizzlies' top rusher with 78 yards on 18 carries. Also for Northside, Bolton rushed for 55 yards on 11 carries. He had 54 yards on nine carries in the second half. Clayton caught two passes for 62 yards, both coming in key situations on the Grizzlies' two second-half TD drives.

The Grizzlies finished with 320 yards of total offense, 175 rushing and 145 through the air.
