New Mexico State linebacker Trashaun Nixon tackled Abilene Christian wide receiver Taylor Gabriel at the 6 yard line to preserve the Aggies first win of the season, 34-29.
New Mexico State (1-7) trailed the FCS Wildcats at halftime, 22-21.
The Aggies took the lead in the fourth quarter on a pair of field goals from Maxwell Johnson and a 5-yard touchdown run by Germi Morrison to make it 34-22 with 2:32 left.
But Abilene Christian (5-4) rallied. John David Baker found Charcandrick West with a 5-yard touchdown pass with 19 second left and the Wildcats recovered an on-side kick.
After a 15-yard personal foul penalty on the kick-off and a 10-yard holding penalty, Abilene Christian had the ball at its own 21. On the final play Baker found Monte Green-Avery with a 59-yard pass, and a lateral to Gabriel collected another 14 yards before Nixon's tackle ended the threat.
