On Friday afternoon, the Federal Aviation Administration (FAA) issued a nationwide ground stoppage for all departing flights due to "extraordinary circumstances and reasons for safety." That announcement came as numerous college football programs were preparing to leave for road games acrossy the country.

There is no timetable for when the issue will be resolved, and that has left teams scrambling for alternate plans. Fortunately, some teams have already arrived at their destination, but quite a few high-profile matchups could be affected by the disruption.

At the moment, there are a handful of top-25 teams that still haven't taken off, and they are looking for alternate forms of transit. That raises another set of questions, including timing and player safety. What if these teams can't get the proper rest after spending most of Friday night on a bus, and will games have to be pushed back due to late arrivals?

Those are questions without answers at the moment as neither the NCAA nor the inidividual conferences have addressed how the ground stoppage might affect Saturday's schedule.

For now, here is the latest on how notable Week 11 matchups have been affected by the FAA's ground stoppage.

Northwestern at No. 20 Ohio State
