The Titans have earned a postseason berth for the first time since the 2008 season.
Tennessee staved off a comeback attempt by first-place Jacksonville, ending a three-game losing skid with a 15-10 victory in Week 17.
Marcus Mariota came up big with the game on the line, moving the sticks with a pair of tackle-breaking, stiff-arming runs to drain the clock and preserve the win. The embattled quarterback's 61 rushing yards led the team, making up for a botched handoff that was returned 67 yards for a Yannick Ngakoue touchdown earlier in the fourth quarter.
Coach Mike Mularkey can also thank his stingy defense and a mistake-prone Jaguars outfit for saving his job.
Sunday's tilt turned on a late first-half sequence which saw fumbles by punt returner Jaydon Mickens and wideout Keelan Cole converted to easy field goals. Presented an opportunity to drive for a tying field goal, Jacksonville ended up entering halftime with a 12-3 deficit. The second half brought more blown opportunities for Doug Marrone's team, as rookie wideout Dede Westbrook dropped a 34-yard touchdown and Blake Bortles was intercepted twice by safety Kevin Byard.
