The interior of Chicago’s offensive line remains fluid with one week left until players report to training camp. A host of players will compete in the preseason for the starting left guard and center positions, including 2016 second-round choice Cody Whitehair, Ted Larsen, Hroniss Grasu and Silatolu.
The Bears held Larsen out of mandatory minicamp for precautionary reasons, but he is expected to be ready when the club arrives in Bourbonnais.
An undrafted rookie out of Dartmouth, Williams participated in Chicago’s 2016 rookie minicamp before signing a contract in June. The Bears now have four quarterbacks on the 90-man offseason roster following Williams' release.
