Apertura 2008
The Primera División A Apertura 2008 is a Mexican football tournament, one of two short tournaments held each year. It began on July 18, 2008, and ran until December 7, 2008. The reigning champions, León, were eliminated in the quarterfinals by Irapuato on a 2–1 two-leg aggregate, and thus could not successfully defend their Clausura 2008 title. Querétaro won the tournament, defeating Irapuato on a 2–0 two-leg aggregate, and will earn a spot into the promotional playoff held after the end of the Clausura 2009 season, where the winners of the two tournaments meet in an effort to gain promotion to the Primera División.
After winning the 2008 promotional playoff against León, the Indios were promoted to the Primera División. Veracruz were relegated to the Primera División A due to finishing at the bottom of the Primera División relegation table.
