The switch was made to give residents and emergency workers in Florida ample time to prepare for the arrival of the storm, in case it makes landfall in the state.
It's the second time a Dolphins opener has been moved because of a hurricane. In 1992, the opener between the Dolphins and New England was moved because South Florida still was dealing with the aftereffects of Hurricane Andrew and the game was postponed to Oct. 18 when both teams had their bye.
The Dolphins and Titans have different bye weeks this season, which made moving the game up one day the most logical option.
The game has been declared a sellout and will be televised by CBS in the Tennessee and South Florida regions. It also will be available on the NFL's Sunday Ticket.
Preparing for a season opener with a hurricane looming isn't the most ideal scenario, but the Dolphins are trying to cope as best they can.
"It can be distracting," said linebacker Zach Thomas. "But you keep working. Hopefully, guys won't be focused on that because if we are, we'll definitely get a good beat-down, because we are playing a great team."
