The 1968 Astro-Bluebonnet Bowl was the first Bluebonnet Bowl that had "Astro" in the title, which would stay that way until 1984. It had what was at the time the largest crowd to see a game indoors, played by the SMU Mustangs of the Southwest Conference and the Oklahoma Sooners of the Big Eight Conference. The game was a low-scoring affair until the fourth quarter, which had 35 combined points and most notably ended on a missed conversion.
