'Black Monday' as it is called in the NFL - the day after the regular season ends when most coaches are typically let go - is over.

Here's what you need to know about who's out, who's on thin ice and who's safe for 2015.

First, here's the teams who have fired their coaches as of Tuesday morning.

Chicago Bears: The Bears fired Head Coach Marc Trestman and General Manager Phil Emery on Monday along with Offensive Coordinator Aaron Kromer. The Bears have retained former Giants GM Ernie Accorsi, and reportedly want to hire a new GM before choosing a new coach.

Atlanta Falcons: The Falcons fired Head Coach Mike Smith Monday after 7 seasons with the team. Initial reports are that Falcons GM Thomas Dimitroff is safe. The Falcons are already on the coaching search though, requesting to speak with Denver OC Adam Gase and Patriots OC Josh McDaniels.

Several other assistants are also being considered for Atlanta's top job according to NFL.com.

NY Jets: The Jets cleaned house on Monday, firing both Head Coach Rex Ryan and GM John Idzik. Gang Green will reportedly interview Seahawks DC Dan Quinn and Offensive line coach Tom Cable this weekend.

San Francisco 49ers: The Niners and Coach Jim Harbaugh mutually decided to part ways on Monday and Harbaugh was officially announced as the new Head Coach at the University of Michigan on Tuesday. Candidates for the job include 49ers Defensive line coach Jim Tomsula, as well as Dan Quinn, Adam Gase and Josh McDaniels.

Coaches on thin ice

Oakland Raiders: Interim coach Tony Sparano wants the job and many talking heads believe he deserves it, but GM Reggie McKenzie has said while Sparano will get an interview, so will Niners assistant Eric Mangini and Broncos DC Jack Del Rio.

Buffalo Bills: Head Coach Doug Marrone and GM Doug Whaley should be safe, especially after a 9-7 season, but new owner Terry Pagula could possibly shake things up. NFL.com says Marrone meeting with media Monday was a good sign that he will stay.
