Tulane quarterback Jonathan Banks was ruled down short of the goal line on what would have been the winning touchdown Saturday at SMU.
The Green Wave trailed 41-38 when Banks took a snap with 9 seconds left on first-and-goal from the 1 and tried to score on a keeper around the left end.
Although replays appeared to show the ball might have crossed the goal line before his knee hit the turf, there was not enough visual evidence to overturn the ruling on the field.
The loss prevented Tulane from winning a sixth game that would have secured bowl eligibility for the first time since 2013.
