Mularkey: Titans quarterback Marcus Mariota has fractured fibula

It was a ninth consecutive defeat on the road in the division for the Titans (8-7), while the Jaguars enter Christmas with a slightly improved 3-12 record for the season.

The playoffs haven't been thought of much by the Jaguars during a disappointing season, but this one felt good for a team that avoided becoming the first in franchise history not to win in Jacksonville.

An air cast was put on his injured right leg and the quarterback was lifted onto a medical cart. But it has to be said: He was shockingly ineffective in this game before the injury, an unexpected development that killed the Titans' chances of overcoming their banged-up defense.

The letdown was worsened following Mariota's injury, which abruptly ended his breakout season.

I don't think they weren't ready.

Titans quarterback Marcus Mariota is having surgery to fix his broken fibula Wednesday, and the hope is that he won't miss much offseason work, if any. On the Jaguars first drive he hooked up with Marquise Lee for a 21-yard touchdown.

Matt Cassel will get the start in Sunday's season finale against the playoff-bound Texans, with Alex Tanney to be added from the practice squad as a backup.

Bortles finished the game 26 of 38 passing for 325 yards with one touchdown and no interceptions.

Rookie cornerback Jalen Ramsey had a pick six to ice the game and it was Ramsey's second interception in as many weeks. Chris Ivory dominated the ground game with 14 carries for 45 yards and 1 touchdown.

Tennessee needed the Bengals to win to set up an AFC South title game next week against the Texans.

"Cassel is a guy who's been around a long time and has won a lot of games", Titans running back DeMarco Murray said.

While scrambling away from defenders, Mariota was tackled awkwardly by Jaguars rookie Sheldon Day.
