The Miami Dolphins have fired Josh Boyer as defensive coordinator after four seasons with the franchise. 

"I am grateful for Josh's contributions this year and throughout his tenure with the Dolphins," Mike McDaniel said in a statement. "The defense made strides through the season, so coming to this decision was not easy, but ultimately I feel it is in the best long-term interests of the Miami Dolphins and the continued growth of our players and team."

While Miami owned the league's fourth-best run defense, it also ranked 21st in defensive expected points added, 22nd in sacks per pass attempt, and 24th in points allowed per game and third-down percentage.
