It's the most nerve-wracking time of the year for NFL coaches on the hot seat -- Black Monday -- and some guys are already without a job ... including Ron Rivera and Arthur Smith.
The Commanders made their announcement just minutes ago ... saying after four seasons with the franchise, it was time to move on from Riverboat Ron.
Rivera went 26-40-1 during his time on the sidelines ... including one playoff appearance in 2020 after winning the NFC East. He won Coach of the Year honors that same season.
During that period, Rivera fought a bout with squamous cell carcinoma, but did not miss a single game while receiving treatment.
The Commanders will be a sexy option for coaches -- they have the No. 2 overall pick in the upcoming draft ... and new owners Josh Harris and Magic Johnson are eager to turn the franchise around.
The team has hired former Golden State Warriors GM Bob Myers to help with its coaching search, according to reports.
As for Smith, the Atlanta Falcons decided to give him the ax on Sunday ... after going 7-10 each of the past three seasons.
Falcons head coach Arthur Blank addressed the move in a statement ... saying, "Decisions like this are never easy and they never feel good."
"We have profound respect for Coach Smith and appreciate all the hard work and dedication he has put into the Falcons over the last three years. He has been part of building a good culture in our football team, but the results on the field have not met our expectations."
"After significant thought and reflection, we have determined the best way forward for our team is new leadership in the head coaching position."
There may be more moves coming ... and many are speculating Patriots head coach Bill Belichick may be on the move as well, even though he remains under contract.
