Chip Kelly won't be the offensive coordinator for the Jacksonville Jaguars.

The former San Francisco 49ers head coach interviewed for the position, but the Jaguars decided to retain Nathaniel Hackett, the team announced Wednesday evening.

"After taking over as the play-caller in 2016, the offensive unit made a significant jump under the direction of Nathaniel Hackett," Jaguars Executive Vice President of Football Operations Tom Coughlin said in a statement Wednesday. "Nathaniel comes from a coaching family and is truly ardent about the game of football, which is contagious to his players and the assistants. He has a long history of working alongside Coach Marrone and we are fortunate to have him on our coaching staff."

Kelly was thought to be the frontrunner for the position because of his history with Coughlin, the former coach of the New York Giants. Coughlin tried to hire Kelly when he was with the Giants. Instead, it was Hackett's history with first-year Jaguars coach Doug Marrone that may have proved decisive.

Hackett was the team's offensive coordinator for the second half of the 2016 season after former coach Gus Bradley fired Greg Olson and promoted Hackett. Hackett served as offensive coordinator when Marrone was the head coach of the Buffalo Bills from 2012-2013 and under Marrone at Syracuse University in 2011-2012. Marrone was named the Jaguars interim coach after Bradley was fired in 2016.

The Jaguars, who finished the season with a 3-13 record, decided to keep their major coaching hires in-house. They promoted their offensive line coach to head coach and retained their offensive and defensive coordinators.

Kelly also interviewed for the Jaguars head coach position, but the team promoted Marrone.

Kelly was fired by the 49ers after just one season. The 49ers posted a 2-14 record and lost a franchise-record 13-consecutive games during the 2016 season.
