With the #NFL regular season drawing to a conclusion on Sunday, it has been reported that several head coaches will likely be on the sidelines with their current team for the last time.

As of now, five #Head Coaches are not expected to be back (not including Steve Spagnuolo, the Giants’ interim coach who took over for fired Ben McAdoo).

Many thought the list would be longer but coaches such as Bill O’Brien with the Texans and Dirk Koetter with the Buccaneers will reportedly be back. Todd Bowles of the Jets signed a contract extension.

Of course, there still may be more head coaching openings once the offseason begins. For now, here are the head coaches not expected to be back next season.

Arizona Cardinals - Bruce Arians

The 65-year-old Arians is expected to step down after this week's game. He is a former two-time Associated Press Coach of the Year (2012 when he went 9-3 as interim #Head Coach with the Colts and 2014 when the Cardinals went 11-5). Entering Week 17, Arians has a career 48-30-1 mark with Arizona.

Chicago Bears - John Fox

It is likely that the 62-year-old Fox will be coaching his last game with the Bears on Sunday as he is not expected to be retained. Entering Sunday, Fox owns just a career record of 14-33 with Chicago in three years. He experienced plenty more success in previous head coaching jobs with the Panthers and Broncos, and he has a career 133-122 record in 16 years as a head coach.

Cincinnati Bengals - Marvin Lewis

It was reported a few weeks ago that Lewis was not expected to be back with the Bengals in 2018.

The 59-year-old has been their head coach for 15 years now and has a record of 124-112-3 manning the team. They made the playoffs seven times in his tenure but were one-and-done every time. He was the Associated Press Coach of the Year in 2009.

Detroit Lions - Jim Caldwell

The 62-year-old Caldwell could lead the Lions [VIDEO] to their third winning season in his four years if they win on Sunday, but reports are that he will no longer be with the team next season. He is 35-28 with Detroit and has led the team to two playoff berths (0-2 in postseason). He previously was the head coach for the Colts from 2009-11 where he went 26-22 and led Indianapolis to the Super Bowl in his first season (lost to the Saints).

Indianapolis Colts - Chuck Pagano

The 57-year-old Pagano is not expected back with the Colts [VIDEO] next season after spending the last six as their head coach. Entering Sunday, he has a career 52-43 record (43-40 if the 12 games he missed in 2012 for cancer treatments aren't counted). Indianapolis has missed postseason play each of the last three years and have bottomed out at 3-12 this year.
