Former Chicago Bears and Green Bay Packers guard Josh Sitton has a two-year agreement in place with the Miami Dolphins, a source told ESPN's Adam Schefter.
The move comes on the same day as news that guard Jermon Bushrod is leaving the team to join the New Orleans Saints and center Mike Pouncey has requested to be released.
The Bears declined to pick up an $8 million option to retain Sitton, a four-time Pro Bowl selection, for the 2018 season on Feb. 20.
The 31-year-old missed the final two games of the 2017 season with an ankle injury and also battled through a rib injury.
