That is correct. The NFL has a scheduling rule that teams in the same division do not play each other in the preseason.Mark L.

This will the be first time they have met in the pre-season. The only other team the Vikings have not played in the pre-season is Green Bay. Anyone know about other teams that have never played against each other in the pre-season.
(Addendum-- unless Dallas Texans vs. New York Titans in preseason counts)
