Three NFL head coaches and two general managers were the first firings on the morning after the regular season ended, according to reports.

The Chicago Tribune is reporting that Chicago Bears coach Marc Trestman, a native of St. Louis Park, and general manager Phil Emery have been fired.

The Tribune story said: "Emery's exit is directly tied to the failures of Trestman, the head coach he handpicked in 2013 after firing Lovie Smith. Emery chose Trestman as his team's new leader over fellow finalist Bruce Arians, a move that has been widely skewered with Arians reviving the Arizona Cardinals and guiding them back into the playoffs while the Bears have plummeted toward the bottom of the NFC."

The New York Jets have fired coach Rex Ryan and general manager John Idzik after one of the most disappointing seasons in franchise history.

Atlanta has fired head coach Mike Smith after the Falcons lost 34-3 at home against Carolina on Sunday in a game that decided the title in the weak NFC South, in which every team finished with a record below .500.

Albert Breer of the NFL Network is reporting that Jim Harbaugh has agreed to take the head coaching job at the University of Michigan after leaving the San Francisco 49ers.

Here's a report from ESPN on the Harbaugh-to-Michigan news.

With the Jets (4-12) failing to make the postseason for the fourth straight season, owner Woody Johnson opted to clean house Monday and start fresh with a new coach and GM.

Ryan was 50-52, including 4-2 in the postseason in his six seasons with the Jets. His first few years were filled with guarantees, bold statements and two consecutive trips to the AFC title game. But in the end, there were not enough wins to back up all the big talk.

Idzik lasted just two seasons after replacing the fired Mike Tannenbaum in 2013. He was heavily criticized this year for questionable personnel decisions in the NFL draft and free agency.

Atlanta had a 66-46 regular-season record with Smith and won two NFC South titles. But this season ended at 6-10.

"Smitty's contributions to our club, team and city over the last seven years are numerous," Falcons owner Arthur Blank said in a statement released by the team. "His accomplishments on the field made him the most successful coach in the 49-year history of the Falcons, and we are grateful for the foundation he has laid for us for the future."

Smith joined the Falcons with general manager Thomas Dimitroff in 2008. Quarterback Matt Ryan was the new management team's first draft pick, and the three combined for instant success with five straight winning seasons.

Before Smith was hired, the Falcons never had back-to-back winning seasons. He immediately raised expectations with an 11-5 finish in his first season. The Falcons won 10 or more games in four seasons under Smith, including 13-3 finishes in 2010 and 2012. Smith reached 50 wins in only 71 games, the third-fastest pace since the 1970 AFL-NFL merger.

Smith, however, had a 1-4 record in the playoffs. Following a trip to the NFC championship game in 2012, the Falcons have fallen to 10-22 the last two seasons.

Before he was hired by the Falcons, Smith was the defensive coordinator for the Jacksonville Jaguars from 2003-07. He was a defensive assistant with Baltimore from 1999-2000.

In a press release on the Smith firing, Falcons owner Arthur Blank said: "Smitty's contributions to our club, team and city over the last seven years are numerous. His accomplishments on the field made him the most successful coach in the 49-year history of the Falcons, and we are grateful for the foundation he has laid for us for the future."
