The Jacksonville Jaguars have fired offensive coordinator Greg Olson.

Quarterbacks coach Nathaniel Hackett will take over playcalling duties. He previously served as the offensive coordinator with Buffalo in 2013-14 under head coach Doug Marrone, who is now the Jaguars' offensive line coach.

"Greg was a tremendous asset and always put all of his effort in doing everything he can to help in his players' improvement," Gus Bradley said in a statement. "He did some great things with our offense over the past two seasons, and for that, we are very appreciative.

"After a thorough evaluation, I came to the conclusion that with the direction that our offense was headed, it was best to make a change moving forward."

The Jacksonville Jaguars won't make a coaching change despite back-to-back embarrassing losses.

After the team's 36-22 loss to the Tennessee Titans on Thursday night, owner Shad Khan said, "Actions speak louder than words. Very little for me to say." He later added that Gus Bradley would not be fired.

A source close to the team confirmed that Bradley will not be fired. The coach is 14-41 in four seasons.

Shad Khan met with Jacksonville Jaguars players and coaches on Monday night in the wake of his 54th loss since he purchased the team in 2011, according to sources.

The meeting was at the team facility, and the tone was reportedly not confrontational.

Khan asked several players their opinion of why the team has struggled this season, and several other players spoke on their own, according to the source.

Blake Bortles deferred to the Jacksonville Jaguars' coaching staff, but made it clear on Wednesday that he's more comfortable when the team takes an up-tempo approach on offense.

The Jaguars adopted an up-tempo approach last Sunday against the Chicago Bears when trailing 13-0. From the 1:53 mark in the third quarter, Bortles was 13-of-18 passing for 187 yards with a touchdown. Prior to that he had been 7-of-15 passing for 84 yards with an interception.

"We were able to find a rhythm," Bortles said. "I thought we did a good job kind of handling the adversity."

When asked if he thought the Jaguars should switch to the approach sooner against the Oakland Raiders this weekend, Bortles deferred.

"I think that's something for [Greg Olson] and Gus [Bradley] to decide on," he said. "It's good to have it, have confidence in it and know we have it if we need it."

Bortles pointed out why a faster pace helps him.

"It's easier to find a rhythm, I believe," he said. "I feel comfortable in it. I feel good in it. Our offense feels good and comfortable in it and we do a good job moving the ball."
