Tannehill, who hasn't appear in any playoff games since Miami drafted him eighth overall in 2012, will back up Titans starter Marcus Mariota. The Dolphins get a fourth-round pick in 2020 and a 2019 seventh-round pick, and the Titans get Tannehill and a 2019 sixth-round pick according to NFL Network's Ian Rapoport.
The 30-year-old Tannehill has been the Dolphins starting QB since he was drafted with the eighth overall pick of the 2012 National Football League draft out of Texas A&M.
Stay tuned here at Dolphins Wire for updates to this developing story.
Tannehill threw for 17 touchdowns to 9 interceptions in 2018.
Two great quarterbacks but maybe not quite what the Dolphins are looking for. There aren't many quarterbacks on the free-agent market, either, who could potentially serve as an effective bridge between now and the time when Miami anoints its next franchise quarterback.
The injuries also sapped some of what made Tannehill an intriguing quarterback early in his career: athleticism, ability to make plays when they break down and a strong arm with precise accuracy. Titans general manager Jon Robinson got creative in a trade to find the best option to fill the role. The belief is Miami might be willing to eschew taking a quarterback in the first round this year in order to set itself up to take one in next year's draft. Tannehill earned a ideal 158.3 passer rating and was rewarded by being named AFC Offensive Player of the Week.
