In Tennessee, Tannehill will back up starter Marcus Mariota.
Stay tuned here at Dolphins Wire for updates to this developing story.
A source close to the former 49ers quarterback made it known he is interested in joining the Dolphins, according to a CBS Sports report.
Tannehill will not count against the Dolphins salary cap in 2020.
Tannehill's time in Miami was marked by his lack of availability due to injury and inability to get the Dolphins over the playoff hump.
Tannehill entered the league in 2012 as the eighth overall pick with the Dolphins, but he never lived up to his lofty draft status.
He departs Miami with a career 62.8 completion percentage and an 87 passer rating, and left money on the table. But he didn't have enough of them and then injuries really hit, including an ACL injury that wiped out his 2017 season.
For the Titans, they've been looking for multiple seasons to find a top-end backup as injury insurance for Mariota. Now the Titans have multiple options, both for the short- and long-term. He's also playing on a fifth-year option worth $20.9 million and he's set to be a free agent after the season. Tannehill earned a flawless 158.3 passer rating and was rewarded by being named AFC Offensive Player of the Week. Dan Marino's career passer rating was 86.4, but he played under different rules and there's no one who would argue about him being the greatest quarterback in franchise history.
