The Chicago Bears have signed free-agent G Josh Sitton to a three-year deal worth $21.75 million, with $10 million guaranteed.

Sitton was a 2008 fourth-round draft pick of the Green Bay Packers, where he's played his entire eight-year career. He has started at both guard spots for the Packers, earning Pro Bowl nods in 2012, 2014 and 2015. He was named All-Pro in 2013 and 2015.

He was due $6.5 million this season and Green Bay cut him just before the 53-man roster deadline on Saturday.

With Sitton and Kyle Long, the Bears now have a pair of three-time Pro Bowl guards. Second-round rookie Cody Whitehair will either slide inside to center or serve as the swing guard.

From the official press release:

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.
