INDIANAPOLIS — Colts head coach Shane Steichen declined to confirm Thursday’s NFL Network report that starting quarterback Daniel Jones is playing through a fractured fibula.

What Steichen would say about the injury is that Colts doctors are confident that Jones will not make the injury worse by playing.

Jones played all 51 snaps against Kansas City last week, and Indianapolis is not concerned enough about the injury to bring No. 3 quarterback Brett Rypien up from the practice squad.

“Daniel was a full participant today,” Steichen said. “Obviously, he’s dealing with the fibula. He’ll be ready to go for Sunday. Again, talking to our trainers and our doctors, Daniel himself, we’d never put him out there if we thought something could go wrong there.”

Asked again if Jones has a fractured fibula, Steichen stuck to the same statement he used last week.

“I’m not going to get into the specifics of that,” Steichen said.

Jones is not sure when he suffered the injury.

The Colts quarterback returned from the bye last week and practiced in full on Wednesday, then felt something in his calf on Thursday and talked to the trainers. When the Indianapolis doctors examined the injury, the issue was found in the fibula, an injury the NFL Network has reported as a fracture.

Neither the Colts or Jones’ representatives have been willing to confirm that report.

Jones has been adamant that he’s going to play.

“Our trainers and doctors have cleared him to play,” Steichen said. “He’s good to go. He wants to play.”

Indianapolis has not changed the playbook due to the injury.

But the Colts do not have to change a lot materially. Indianapolis has not used Jones the same way he was used in New York; the Colts have rarely called designed runs for the quarterback outside of quarterback sneaks.

“We’ll manage, but again, we’re not going to limit anything that we do offensively from a game plan standpoint, what he feels comfortable with out there,” Steichen said. “He’s ready to go.”

Indianapolis plans to stick with rookie quarterback Riley Leonard as the backup.

Third-year quarterback Anthony Richardson remains on injured reserve after undergoing surgery to repair an orbital fracture, and the Colts have decided to stick with Leonard rather than elevating the veteran Rypien into the No. 2 spot.

Leonard has played six snaps this season.

“He’s getting a lot of the scout-team looks,” Steichen said. “He’s getting a ton of that stuff, going through the game plan, preparing the right way, and he’s made good strides in that area.”
