JACKSONVILLE – New day, same story.

The story is the Jaguars' quarterback position, and Monday's news was not much changed from Sunday or Saturday:

Blake Bortles and Chad Henne are competing for the position.

And Head Coach Doug Marrone said while he has an idea about playing time for the duo in Thursday's Preseason Week 3 game against Carolina, he's not yet sharing that idea publicly.

"I have a plan in in my mind," Marrone said Monday after the Jaguars worked for a little more than two hours in the Daily's Place Flex Field adjacent to EverBank Field. "I haven't talked to the quarterbacks about that plan yet."

While Bortles entered 2017 Training Camp as the team's starter, Marrone last Thursday following a Preseason Week 2 loss to Tampa Bay met with the Bortles and Henne and informed the pair the quarterback position was "up for grabs."

Bortles, the starter since Week 4 of the 2015 season, started and worked four series with the starters against Tampa Bay. Henne played two series with the starters in a span that began late in the first half and ended early in the second.

"We'll see how practices go," Marrone said. "We have another big day tomorrow. Both of them are doing fine. I feel like I have a very good plan for myself and then I'll make the quarterbacks aware of it as we get closer to the game."

Marrone said Saturday the pair would split repetitions in practice this week, and that he likely will tell the quarterbacks the playing time plan for Thursday on Wednesday at the team hotel.

"I've got a plan," Marrone said. "I don't want to discuss it because I still have to discuss it with them. Plus, I've still got another practice. I want to make sure I tell the quarterbacks with what I feel is a good amount of time to get themselves prepared. I want to get all the information and I want to make sure of the direction I'm going and that I'm doing what's best for the team.

"I've written a couple of scenarios down, and I feel good about one of them. We'll see where it goes."

Marrone was asked Monday if the quarterbacks had responded to the situation.

"It's a challenge," Marrone said. "They're both competitive guys, so you'll have to ask them how they feel about it. I'm just evaluating how they play on the field."

Marrone on Monday also addressed the team's left-guard position, saying the team continues to look at multiple players after starter Patrick Omameh struggled there against the Buccaneers.

"We've been rotating some players," Marrone said. "It's the same type of situation [as quarterback]; we're trying to find someone who will go in there and take the position."

Marrone said former starting center Luke Bowanko was a possibility at the spot.

"He's heavily involved in that mix," Marrone said.
