The Miami Dolphins announced on Sunday that they agreed to a four-year contract with San Francisco 49ers offensive coordinator Mike McDaniel to become the team’s new head coach.

McDaniel, who is biracial, takes on his first head-coaching position at any level after 15 seasons in the NFL and two in the United Football League. After being promoted in January 2021, he served as San Francisco’s offensive coordinator for one season.

The Dolphins’ coaching search has been hampered by the class-action lawsuit filed by fired coach Brian Flores, who claims rampant racism in the NFL’s recruitment and retention of African-American head coaches.

Meanwhile, the 49ers hired Anthony Lynn, a former head coach of the Los Angeles Chargers, to be an assistant head coach and coordinate the run game, which McDaniel previously did in San Francisco before being promoted to offensive coordinator for the 2021 season.

The Niners QB Jimmy Garoppolo praised McDaniel during the playoff run last month.

“Mike is awesome,” Garoppolo said. “He really is. He’s kind of that, I don’t want to say the mastermind behind everything, but he’s kind of that guy in the background that doesn’t say a whole ton to a lot of people, but his mind is always moving. He’s a lot smarter than most of us. So he dumbs it down for us and kind of gets us all on the same page.”
