According to the NFL Network’s Tom Pelissero, Bush is going on the list due to a close contact away from the team and not because of a positive test. He is already in Nashville but will quarantine away from the team.
Bush has been a member of the special teams this year and he’s also been called on to play in some defensive sub-packages. In six games this season he has 4 total tackles and an interception.
The Bears could elect to promote a player from the practice squad to replace him with the deadline for that move being 90 minutes before kickoff.
UPDATE - On Sunday morning the Bears placed offensive lineman Lachavious Simmons on the Reserve-COVID-19 list and activated the newly signed Aaron Neary, who can play center, to take his place.
According to the NFL Network’s Tom Pelissero, yesterday’s test result came back positive and there have been no high-risk close contacts, although previous reports indicate there were no positive tests from yesterday. Simmons has been quarantined in Nashville.
The Bears reserve o-line now appears to be Neary, Dieter Eiselen, and Badara Traore, with a likely starting five of Charles Leno Jr. (LT), Arlington Hambright (LG), Alex Bars (C), Germain Ifedi (RG), and Rashaad Coward (RT), although don’t rule out Neary getting the surprise start at center since that’s his natural position.
