Chase Jackson picked off a pass at the 10 yard line and the Rams averted the Cardinal score with 23.6 seconds left in the half.
The refs blew a call on the 2nd half kickoff that would have put the Rams at their own 35. The Rams got a re-kick and Jackson returned it from the 20 to the 45.
With 3 receivers to the left, Duckett hit tight end Luke McConnell in the middle in the field for 19 yards to the Warrensburg 32.
On 3rd and 5, Duckett hit McConnell again and his run after the catch got the 1st down at the Cardinal 16. Jackson ran for six yards and Hendryx for one, before another procedure flag pushed them back to the 19.
Duckett threw a fade pattern to Wyatt Fox, who got separation by pushing off inside the 5 and made the catch for a game-tying TD. There was no flag so the TD stood. The Dylan Patch kick was blocked by a defender who raced around the outside of the line and, with 6:46 left in the 3rd, it was 6-6.
Warrensburg took the kickoff, but defensive plays by Jared Finley and Mike Ulrich brought 4th down. A fake punt was stopped short of the 1st down by Zach Williams and the Rams got the ball at the Warrensburg 32.
Devin Peterson ran 13 yards for a 1st down at the Cardinal 14. Tice Robinson ran twice and the official measurement proved a 1st down at the Cardinal 2 yard line.
Duckett kept the ball up the middle and Elliott Smithson and Andrew Mudgett kept pushing the pile over the goal line with 2:30 in the 3rd. The fake kick didn't work and Shelby was up 12-6.
The Cards took the kick, but on 3rd and 4, Finley sacked the QB again. After the punt, the Rams had the ball at the Cardinal 47.
