(AP) — There are now six NFL teams currently in the market for head coaches.

The list doubled on Monday as the Bears fired John Fox and the Lions parted with Jim Caldwell, while Bruce Arians retired as the Cardinals' head coach.

Fox went 14-34 in three seasons with Chicago, giving him a .292 winning percentage that is second-worst in team history. The Bears had double-digit losses in each season under Fox and completed a 5-11 campaign on Sunday.

Caldwell was Detroit's most successful coach in the Super Bowl era, going 36-28 in four seasons but 0-2 in the playoffs. The Lions finished 9-7 on Sunday but were eliminated from postseason contention the previous week.

The 65-year-old Arians has stepped aside following a five-year run with Arizona. He was 49-30-1 with the Cardinals, including a 13-3 mark and an NFC title game appearance in 2015. But the Cards went 15-16-1 over the last two years, including an 8-8 mark this season.

The departures were announced one day after Oakland's Jack Del Rio and Chuck Pagano of Indianapolis lost their jobs. The Giants will be interviewing coaching candidates after firing Ben McAdoo in December.

Vance Joseph will remain head coach of the Broncos despite a disappointing 5-11 season that included the team's longest losing streak since joining the NFL. Denver collapsed amid a quarterback carousel in Joseph's first year at the post.

In Cincinnati, coach Marvin Lewis talked to owner Mike Brown about his future with the Bengals and plan to have more discussions. The Bengals failed to make the playoffs for the second straight season, and Lewis' contract is finished after his 15th year in Cincinnati.
