The Bears on Wednesday released quarterback Mike Glennon, receiver Markus Wheaton and cornerback Marcus Cooper.
General manager Ryan Pace had said Feb. 28 at the NFL Combine that the team would release Glennon after the start of the league year.
After signing with the Bears last March, Glennon was anointed the No. 1 quarterback. He remained in that position even after Mitchell Trubisky was selected with the second pick in the draft. But Glennon was replaced by Trubisky after four starts, having completed 66.4 percent of his passes for 833 yards with four touchdowns, five interceptions and a 76.9 passer rating.
Wheaton appeared in 11 games last season, catching three passes for 41 yards.
Cooper played in 15 games with four starts in 2017, recording 13 tackles, three passes defensed and three special teams tackles.
