Chicago Bears head coach Matt Nagy will miss Sunday's game with the San Francisco 49ers as he remains in coronavirus quarantine.

Nagy tested positive for COVID-19 on Monday, leaving special teams coordinator Chris Tabor to take charge of practice this week.

And it is Tabor who will take the reins on Sunday as the Bears look to improve to 4-4 in a meeting with the 2-4 Niners.

Tabor is in his 14th season as an NFL assistant and must use that experience to lead the Bears to victory in a game between two teams fighting to stay alive in the NFC playoff picture.

The Bears follow the Arizona Cardinals in being without their head coach for a game because of COVID issues.

Arizona defeated the Cleveland Browns in Week 6 in a game coach Kliff Kingsbury missed after testing positive.

The Bears won their most recent meeting with the 49ers in 2018 but have lost two of their previous three home games against San Francisco.
