From the press release of the Chicago Bears:
The Chicago Bears have signed OL Josh Sitton to a three-year deal.
Sitton, a three time pro bowler (2012, 2014-15), has started 112-of-121 games over eight seasons with the Green Bay Packers. He owns 64 starts at right guard, 47 at left guard and one at left tackle. Over the course of his career, the UCF alum has garnered numerous honors, including 2010 Offensive Lineman of the Year (NFL Alumni Association), first-team all-Pro (Sporting News 2014), first-team all-NFL (PFWA, 2014), second-team all-Pro (AP, 2013-15) and was named a Pro Bowl alternate in 2010-11 and '13. Sitton helped the Packers offense rank first in the NFL in scoring (30.4), sixth in yards per game (386.1) and tied for first in giveaways with a franchise-record low 13 in 2014. He was also part of an offensive line that tied for ninth in the league in sacks allowed with 30 in 2014. In 2013, he helped the Packers offense finish seventh in the NFL in rushing yards and sixth in rushing yards. Sitton was part of an offense that set Green Bay records in points (560), total net yards (6,482) and total net passing yards (4,924) in 2011.
We will update with contract details as soon as they are available.
This is a huge upgrade for the Bears offensive line, and we mentioned yesterday there was a possibility that Chicago wouldn't let him leave Halas Hall without signing a contract.
