The Bears on Tuesday made the following roster moves:
• Outside linebacker Robert Quinn was placed on the reserve/COVID-19 list.
The roster designation was created last year for players who either test positive for COVID-19 or who have been in close contact with an infected person.
Quinn has performed extremely well so far this season, registering 5.5 sacks, 19 tackles and five tackles-for-loss.
• Safety Deon Bush was put on injured reserve after hurting his quad in Sunday's loss to the Packers. He will miss a minimum of three games. The sixth-year pro has recorded 15 tackles and two pass breakups this season.
• Safety Teez Tabor was promoted from the practice squad to the active roster. He was originally signed to the Bears practice squad last Dec. 23.
Tabor appeared in 22 games with five starts over two seasons with the Lions in 2017-18, compiling 42 tackles. He was selected by Detroit in the second round of the 2017 draft out of Florida.
Tabor spent part of the 2019 season on the 49ers practice squad and remained with San Francisco until being waived July 6, 2020.
• Running back Chris Thompson was signed to the practice squad. Thompson has appeared in 74 games with one start over eight seasons with Washington (2013-19) and the Jaguars (2020), rushing for 1,214 yards and five touchdowns on 257 carries and catching 232 passes for 1,918 yards and 11 TDs. He has also averaged 20.2 yards on 37 kickoff returns.
