The Jaguars are no longer in sole possession of the AFC South lead.
In fact, if the playoffs started after Week 12, the Tennessee Titans would own the division crown.
Both teams are tied at 7-4 but the Titans own the head-to-head tie-breaker over the Jaguars due to a Week 2 win at EverBank Field.
The Jaguars were in position to hold onto a one-game lead over the Titans but lost to the Arizona Cardinals, 27-24, on Sunday.
The Titans were able to bounce back into the division lead following a win over the Indianapolis Colts. The division win has Tennessee in prime position to control its own destiny.
The Colts are all but buried in the race for the division crown. At 3-8, Indianapolis is on the verge of being mathematically eliminated from the entire playoff race.
The Houston Texans are set to play the Baltimore Ravens on Monday Night Football. At 4-6, the Texans need a win to stay relevant in the division and wild card races.
Houston seems like a long shot for the playoffs but the dog-eat-dog nature of the AFC has created an opportunity for a surprise bid.
The Jaguars will face all three division opponents again this season. Jacksonville is currently 2-1 against the division.
If the Jaguars beat the Titans in Week 17, the two teams will split the season series. The tie-breaker would then come down to the two teams' division records if necessary.
The Titans are currently 3-1 against the AFC South.
Jacksonville will host the Colts in Week 13. The Jaguars currently hold the fifth seed in the AFC playoff race.
