The Titans have agreed to a trade with the Miami Dolphins that will send quarterback Ryan Tannehill to Tennessee.

Tannehill, a first-round pick (eight overall) by the Dolphins in the 2012 NFL Draft, will join quarterback Marcus Mariota on the team’s roster.

Blaine Gabbert served as Mariota’s back-up last season. Gabbert was informed on Friday he'll be released by the team.
