Ramirez is coming off a season in which he played in all 16 games at guard and center for the Detroit Lions. Ramirez also played for Bears head coach John Fox as a member of the Denver Broncos from 2011 to 2014. He was the starting center for the Broncos in Super Bowl XLVIII, where they lost to the Seattle Seahawks 43–8.
The Lions acquired Ramirez on the first night of the 2015 NFL draft in a trade with the Broncos.
The Bears also agreed to a one-year deal with offensive lineman Ted Larsen, according to Zach Zaidman of the Chicago Bears Radio Network.
