"It was a hard night," Crescenta Valley Coach Paul Schilling said.
Warnock, who guided the Falcons to their lone CIF championship in 1973, coached in the area for more than 40 years. He died in his sleep at his La Crescenta residence on Wednesday. He was 79.
He was remembered throughout Friday night.
The 30 seniors who Warnock coached on the Falcon freshman team four years ago served as captains. Crescenta Valley held a moment of silence for Warnock before the game.
Lee had 159 yards on the ground in the first half as the Falcons held a 21-20 lead at the half. He slowed down in the second half, and the Spartans capitalized.
La Cañada, which has lost four straight to the Falcons, took a 27-24 lead on Scott Gray's 16-yard touchdown run early in the fourth quarter. Lee fumbled on the Falcons' first play of their ensuing drive, and the Spartans scored another touchdown three minutes later to take a 34-24 lead when Gray hit Matt Faber for an eight-yard score. Lee rushed for just 44 yards, but he scored four times.
Crescenta Valley (2-1) simply returned to its strength in the ground game to close the margin.
"We let a few creases open up and we had trouble putting bodies on them and they exploited it," Spartan Coach Dan Yoder said.
Falcon quarterback Zac Wilkerson had a three-yard touchdown run with 6:18 to play to make the score 34-31.
After the Spartans drove for nearly four minutes, the Falcons had an opportunity to take the lead as they started the game-winning drive on their own 36. Nine plays later, Lee sprinted in for a 14-yard touchdown run and the lead. Captain Bryan Luna, an offensive and defensive lineman for the Falcons, intercepted Gray's pass on the Spartans' first play to seal the win.
The Falcons released balloons with the initials "GW" after the game as Warnock's son, Scott, and his daughter, Julia, looked on.
"The community, the team, and the school meant so much to my dad," Scott Warnock said. "It's just satisfying to see that returned this game."
