Maxwell arrived in Miami prior to the 2016 season as part of a trade along with linebacker Kiko Alonso from the Philadelphia Eagles.
The Seahawks lost an original member of the Legion of Boom for the season when cornerback Richard Sherman tore his Achilles against the Cardinals last Thursday and they're bringing another one of them back to fill his spot on the roster.
Maxwell, a sixth-round pick in 2011, was a member of the Seahawks secondary from 2011-14.
During his two seasons as a starter in Seattle, Maxwell combined for 68 tackles, 27 passes defensed and six interceptions. The veteran corner started opposite of Sherman and played a huge role during the Seahawks back-to-back Super Bowl appearances in 2013 and 2014.
Next SPIDER-MAN Spin-off Movie Will Be MORBIUS, THE LIVING VAMPIRE
Basically, he's the Yuri Boyka of the Spider-Man 'verse, only instead of kicking ass, he bites necks and wears tights. We'll have to wait to see where this Morbius movie goes, as there is no release date yet announced.
In his final season in Seattle, Maxwell started 12 games, spring-boarding into a big free-agent deal with the Philadelphia Eagles.
Schefter is reporting that Maxwell's contract is a one-year deal.
Maxwell fell out of favor with the Dolphins after losing his starting job earlier this season.
He has seven games of playoff experience to his credit, though, and the fact that he played in arguably one of the greatest secondaries in National Football League history during his time with the Seahawks makes him a worthwhile signing.
