The cornerback from Washington became the Bears' first selection when they took him with the No. 39 overall pick.
The Bears got a potential starter opposite Jaylon Johnson by taking the athletic and hard-hitting Gordon.
A first-team, All-Pac-12 pick, he had 46 tackles and two interceptions to go with a team-high seven pass breakups in 12 starts last season.
With Gordon under contract, the Bears' only remaining unsigned draft pick is Jaquan Brisker. The safety from Penn State was taken in the second round at No. 48 overall.
