The Vikings don't know if they will play their preseason games because of the ongoing NFL lockout, but they know their opponents.

The NFL released its preseason schedule on Tuesday despite the uncertainty of its labor situation.

Here is the Vikings schedule of opponents:

Week 1 at Tennessee

Week 2 at Seattle

Week 3 vs. Dallas at Mall of America Field at Metrodome

Week 4 vs. Houston at Mall of America Field at Metrodome

UPDATE: NFL.com originally listed exact dates for the games but has since changed them to TBA.

The Vikings were assured of playing their first two games on the road while the Metrodome roof is being repaired. The team hopes the stadium will be ready in time for its two home games.

This is all assuming the lockout is over by then of course.
