Florida Atlantic quarterback and "Last Chance U" alum De’Andre Johnson will be out indefinitely following a hospitalization last week, Owls coach Lane Kiffin said Monday.

During a conference call with reporters, Kiffin confirmed Johnson — who had posted several videos from Boca Raton Regional Hospital in recent days — sustained a "scary medical condition." Kiffin did not elaborate on what the condition is.

Johnson first posted videos of himself in a hospital bed on Friday night. Sources told The Palm Beach Post that it was unclear if Johnson’s hospitalization was related to the undisclosed injury that has limited him in practices over the past month.

Expected to start for the Owls after signing with the program in December, Johnson rushed for 31 yards on four carries in the Sept. 1 opening loss to Navy. Replacing Daniel Parr in the fourth quarter, Johnson completed two of three passes for five yards and an interception.

Kiffin said it was too early to know if Johnson would return this season. Conor Miller, a transfer from Mt. San Antonio College (Calif.) that played high school at Archbishop McCarthy, traveled with the team to Wisconsin as the third-string quarterback. Former Pahokee star Tyrone Smith is also an option, having walked on over the summer.

Other notes from Lane Kiffin’s conference:

Parr remains the starter: Though Dwyer alum Daniel Parr completed only 9-of-19 passes in Saturday’s 31-14 loss to the Badgers, Kiffin said he’s "seen enough" to start the redshirt sophomore against Bethune-Cookman this Saturday.

"Looking back at the film … there was obviously some good and some bad," Kiffin said of his team’s performance against the then-No. 9-ranked Badgers.

Kiffin said turnovers — Parr and the offense did not give up the ball up once and FAU’s defense got two takeaways — played a key role in the evaluation.

"Turnovers were what kept us in it (against) obviously a very good defense," Kiffin said before acknowledging, "We should have played better on offense."

Parr has completed 28 of his 49 pass attempts for three touchdowns and an interception in two games. Last year’s starter, Jason Driskel, has yet to throw a pass but could see elevated action with Johnson out indefinitely.

FAU’s homecoming: As of Monday afternoon, Kiffin and the Owls have yet to learn when they will be returning to Boca Raton after Hurricane Irma.

Following a scheduled off-day on Sunday, FAU returned to practice at Wisconsin’s facilities on Monday. The University of Wisconsin will be paying for FAU’s amenities and meals during the duration for the Owls’ stay in Madison.

In an update released by the school Monday, FAU announced that classes will resume Sept. 18, and students who live in resident halls can return Wednesday.

"Wisconsin has been awesome to us," Kiffin said. "It’s been a strange four days."

Kiffin also confirmed that Saturday’s game against Bethune-Cookman (6:30, BeIN Sports Network) remains scheduled.
