The Matt Eberflus era is over in Chicago -- the Bears just fired the guy in his third year with the team ... marking the first in-season head coaching move in franchise history.
The news broke on Friday ... less than 24 hours after the Bears' sixth-straight loss at the hands of the Detroit Lions on Thanksgiving Day -- a result that was met with heavy criticism.
With the ball and down 23-20 in the final minute of the game, Eberflus elected not to use a timeout to stop the clock .
