Jackson proved to be the workhorse all night for the Warriors, carrying for a game-high 117 yards on 20 carries.
The Riverside defense rode the wave of momentum on SV's next possession, forcing a punt that gave the Warrior offense good field position at its 44. The drive culminated with Chestnut's 50-yard field goal attempt that fell inches short.
From there, Spring Valley began to put the game away. Dylan Lageman scored from 3 yards out to extend the lead to 21-3 with 7:17 left in the third quarter.
In the final stanza, SV picked up scores on a 10-yard Brewer pass to Trevor Maynard and a 2-yard Cameron Lucas run to compete the scoring.
With the win, the 15th-ranked Wolves remained afloat in the Class AAA playoff race.
"We've put ourselves in position at 5-2 to make the playoffs,'' said Dingess, "but Nitro is dangerous considering their ability to throw the ball. We'll have to be ready," Dingess said.
