This is the Jaguars' first division title since 1999, when they also finished ahead of the Titans and advanced to the AFC Championship Game. The Jaguars were in the AFC Central then and moved to the AFC South when the NFL realigned divisions after expanding to 32 teams.
The Jaguars clinched their first playoff appearance since 2007 by beating the Houston Texans last Sunday.
The Titans beat the Jaguars in Week 2, but they've faded down the stretch, with losses in three straight.
"It definitely sucks that we can't win the South off record," Titans defensive tackle Jurrell Casey said. "At the end of the day, we gonna sweep the division other than losing (one) to Houston. We still can't win the division. That's the part that sucks. They didn't even technically beat us to win the division."
"We ready for them. They been bringing it all season long. They supposedly supposed to be kings of the South. We're ready to see that."
