4-3 Bears at 4-4 Cardinals (-1.5), Sunday 4:05 p.m. ET, CBS (Ian Eagle and Charles Davis)
These are the only two teams remaining for the original NFL, which launched in 1920.
The Bears will try to keep one loss from becoming two, following the Hail Mary debacle that cost them a win over the Commanders. The Bears also will attempt to win on the road for the first time this season.
The Cardinals have won three of four, two straight with walk-off field goals. Rookie receiver Marvin Harrison Jr. has 411 receiving yards and five touchdowns.
