Bears’ Tyson Bagent promoted to second-string QB

Bears rookie quarterback Tyson Bagent is on the Bears’ game-day roster and serving as their second-string quarterback for the first time Sunday.

Veteran Nathan Peterman, who was the team’s second-stringer the first three games of the season, will serve as the emergency quarterback. He can only play if starter Justin Fields and Bagent both get hurt.

From small Shepherd University, Bagent was preseason darling, making the team out of training camp.

“He’s working hard in practice every day,” quarterbacks coach Andrew Janocko said of Bagent on Thursday afternoon. “He studies like a pro. He mimics guys that are in front of him. He mimics the other guys in the room ... He’s working. He’s developing. He’s figuring it out.”

Other Bears inactives include safety Eddie Jackson and cornerback Jaylon Johnson, who were ruled out Friday with a foot and hamstring injury, respectively. Running back D’Onta Foreman is inactive for the third straight game, while the Bears have made receiver Chase Claypool a healthy scratch.

The Broncos, who gave up 70 points a week ago, will be without three of their top defenders: safety Justin Simmons, inside linebacker Josey Jewell and outside linebacker Frank Clark.
