JACKSONVILLE – A lot changed for Blake Bortles this week.

But if life seemed hectic from the outside, the Jaguars' third-year quarterback on Friday said it didn't feel that way on the inside.

"With everything that's gone on, it has been a fairly normal week," Bortles said as the Jaguars (2-5) prepared to play the Kansas City Chiefs (5-2) at Arrowhead Stadium in Kansas City, Missouri, Sunday at 1 p.m.

"It's just football. Somebody's going to call the plays, and then you have to go play. It's not a whole lot more complicated than that. We have to continue to not complicate it."

The Jaguars this week changed offensive coordinators, with Head Coach Gus Bradley promoting Nathaniel Hackett from the quarterbacks coach position. Greg Olson was dismissed on Saturday after 23 games as offensive coordinator.

"I think Nathaniel's done a really good job, being a sparkplug and getting the offense going," Bortles said. "He's obviously done a really good job with the plan, putting it together, and getting everybody to buy in – and of making sure everybody has a good understanding of what we're doing and why we're doing it."

Bortles, who has passed for less than 75 yards in the first half of the Jaguars' past two games, also spent two days this week – Monday and Tuesday – working personal quarterbacks coach, Adam Dedeaux, on mechanics and fundamentals.

"Two days isn't going to fix anything," Bortles said, "but hopefully it's kind of a reminder or a refreshment, I guess, of things to focus on and things to do and things to do in a routine. We talked about feel and trying to create muscle memory.

"Obviously it's hard to do some of that stuff in the middle of the season when you're trying to get ready for a game on Sunday, but he did a good job."

Bradley said this week Bortles looked good in practice, and he reiterated that Friday.

"I thought it went very good considering all the things that have taken place," Bradley said. "I thought he's handled it great. When we watch him out on the practice field all indications are that he's in a good place and everything's been very positive."

Bortles said he feels good entering the weekend.

"I think Sunday will be a good test," he said. "I'm excited for it. It's a good opportunity to see where we're at with a new offensive coordinator. I look forward to it."

Asked if there would be a notable on-field difference Sunday, Bortles replied "I would hope so."

"I guess we'll find out on Sunday," he said.

INJURY UPDATE

Jaguars defensive end Jared Odrick on Friday was ruled out of Sunday's game with a foot/ankle issue. He was the only Jaguars player ruled out for Sunday.

Cornerback Aaron Colvin (calf) is listed as questionable with all other players not listed and therefore expected to be able to play.

QUOTABLE I

"It's very important. In our first team meeting [this week] we talked about it. The guys who have played there, coached there, understand how loud it gets. It can be disruptive in itself."

QUOTABLE II

"I think that from this point on let's evaluate and see where we're at and how it's coming together. I know what's happened in the past. I think now it's more, 'All right let's see what takes place now.' For a couple weeks we were looking at 'OK, what can we do, how can we analyze this, is there anything we can do to help this run game out?' We made some changes, now let's see."
