Smith's run capped a 15-play opening drive for the Knights that featured two conversions on third-and-long, another on fourth-and-five and a near interception that bounced off a Cary-Grove defender's hands and directly to receiver Colton Doll inside the 5-yard line.
Cary-Grove, however, didn't trail for long.
The top-seeded Trojans answered back in only three plays, capped by quarterback Ben McDonald's 16-yard touchdown run.
McDonald's score turned out to be the first of six straight touchdowns for the Trojans, who pulled away for a 38-6 victory over No. 8 Kaneland in the second round of the Class 6A playoffs.
Cary-Grove (11-0) will host Chicago Phillips in the state quarterfinals next weekend. Phillips, the defending Class 5A champion, defeated Prairie Ridge, 24-19, on Saturday.
"That first drive that they had definitely took a toll on our defense," McDonald said. "But we knew it was going to be a battle going into the game, so we just took a second and refocused."
