The San Francisco 49ers can scheme their way around NFL defenses, but no team can prepare for a nationwide flight ban. With a Sunday trip to Dallas expected for Week 10 against the Dallas Cowboys, Kyle Shanahan and his crew will also have to prepare for the FAA's decisions.

Friday's nationwide ground stop has made NFL travel plans unpredictable with the 49ers and Los Angeles Rams unsure whether they will make it to their road games.

Neither team's matchup has been officially postponed by the NFL, and neither team has indicated plans to miss the game. If the restrictions stick around, Saturday departures could turn into a logistical nightmare.

The 49ers need to get from California to Texas for the Cowboys, while the Rams at least have a shorter hop to Arizona for the Cardinals.

The Federal Aviation Administration stopped departures nationwide Friday afternoon following a telecommunications failure affecting air traffic control operations.

Transportation Secretary Sean Duffy said technicians were investigating disruptions involving the country's 22 regional air traffic control centers. The order prevented aircraft from taking off, though flights already in the air could continue toward their destinations.

Officials had not established when normal service would resume, and airlines warned that delays and cancellations could continue even after restrictions were lifted.
