The Bears have a new quarterback, and they assured their right guard returns to block for their new quarterback.
The deal for Ifedi came only hours after the Bears agreed to terms with Andy Dalton.
Ifedi, 26, started all 16 games for the Bears last season.
The Seahawks made Ifedi the 31st overall choice in 2016, and he spent four seasons in Seattle. He missed only four starts in four seasons, seeing action mostly at right tackle but also playing some at right guard.
