A foot injury has bothered Mack since early in the season and the Bears will rest him in hopes of healing it. Coach Matt Nagy said no decision has been made on putting their top pass-rusher on injured reserve, which leaves open the possibility he would play Nov. 8 at Pittsburgh.
Mack has a team-high six sacks but went without one and had one tackle in last week's 38-3 loss to Tampa Bay. He had sacks in five straight games before the loss to the Buccaneers.
The Bears will have outside linebacker Robert Quinn back in the lineup this week after he missed the game with Tampa Bay. Quinn was activated from the reserve/COVID-19 list, along with tackle Elijah Wilkinson.
The Bears also announced tackle Germain Ifedi had been placed on the COVID-19 list. Ifedi was on injured reserve at the time due to a knee injury.
Defensive end Akiem Hicks, return man Jakeem Grant and safety Tashaun Gipson are all questionable for Sunday's games. Hicks (groin) and Gipson (hip) missed last week's game.
