JACKSONVILLE – Doug Marrone isn't worried about the quarterback's health.

Marrone, the Jaguars' head coach, confirmed as much early in his first comments to the media Thursday as the Jaguars resumed preparation for their 2019 regular-season opener.

"We're not concerned about it," Marrone said as the Jaguars prepared to play the defending AFC West Champion Kansas City Chiefs at TIAA Bank Field Sunday at 1 p.m.

Nick Foles, the Jaguars' quarterback, was included on the team's injury report Wednesday with an oblique injury. He was listed as participating full, and Marrone reiterated on Thursday what the team said Wednesday – that Foles is fully expected to play Sunday.

The Jaguars were off Wednesday because of precautions regarding Hurricane Dorian, making Thursday their first full day of practice in preparation for Sunday's opener.

Marrone's availability Thursday was his first since Monday and his first since Foles' oblique issue became public.

Marrone said Foles had been dealing with the issue during "training," but NFL rules did not require the team to disclose the injury until Wednesday. Teams don't release official injury reports until Week 1 of the regular season.

"It's been there for a while," Marrone said. "We just didn't have to report it. Now, we're in the process of, "You want to make sure it's reported. … Obviously, it's most better now than it was before. It's just [it's] the quarterback and if you don't put something down [on the injury report] and something does happen, all hell breaks loose."

Marrone said Foles' injury didn't effect his preseason playing time. Foles, like most Jaguars starters and front-line players, played only in Preseason Week 3 as Marrone structured preseason and training camp to prevent injuries as much as possible.

"He could have played," Marrone said. "It was planned the first couple and the amount of snaps in the third one was planned. That had nothing to do with it. We haven't taken reps away or anything."

Foles is expected to appear as practicing on the Thursday injury report, with the following players also expected to practice with injuries: wide receiver Marqise Lee (knee), left tackle Cam Robinson (knee), linebacker Quincy Williams (knee), linebacker Lerentee McCray (ankle), linebacker D.J. Alexander (hamstring) and defensive tackle Marcell Dareus (elbow).

Left tackle Cedric Ogbuehi (hamstring) and tight end Josh Oliver (hamstring) are not expected to practice Thursday.
