Oliver Stark broke his ankle while filming a stunt for the upcoming tenth season of 9-1-1, requiring surgery before returning to work on the ABC drama.
The injury happened in late August during a sequence involving a firefighter swinging from a car over a set piece and toward a ladder truck.
Stark, who plays firefighter Evan “Buck” Buckley, reportedly rolled his ankle over another performer while carrying out the scene.
The actor’s injury was disclosed in a report published Friday, October 9, 2026, ahead of the Season 10 premiere scheduled for Thursday, October 15.

What happened to Oliver Stark?
Stark’s ankle injury occurred after a stunt double reportedly hurt an ankle while rehearsing the same manoeuvre.
The stunt mechanics were adjusted after the rehearsal incident, but Stark was still injured during the subsequent performance.
He underwent surgery on August 26 and later returned to the production, according to the report.
There has been no indication that Stark’s injury will prevent him from appearing in the new season.
ABC’s official cast biography continues to list Stark as a principal cast member playing Buck, one of the Los Angeles first responders at the centre of the series.
Other injuries reported on the 9-1-1 set
Three other performers were also reported to have suffered stunt-related injuries during the production of Season 10.
One stunt performer reportedly cut an arm on jagged metal attached to a set piece and required stitches at a hospital.
Another performer was hospitalized after an awkward landing on a platform designed to simulate a ground collapse.
That incident reportedly resulted in a broken rib and a minor compressed lung.
The incidents were described as separate events rather than one connected accident.
Even so, the injuries have renewed attention on the safety demands of a series that regularly uses vehicle crashes, fires, falls, rescues and other physically demanding sequences.
Why the injury matters for Season 10
Stark has been a central member of the 9-1-1 cast since the show’s 2018 debut.
Buck is frequently involved in the series’ emergency-response storylines, which often require performers to work around vehicles, elevated platforms, fire effects and complex stunt equipment.
The production’s ability to continue filming after Stark’s injury suggests the show used scheduling adjustments, camera angles, stunt doubles or other production methods to accommodate his recovery.
However, the available reporting does not establish exactly how Stark’s injury will be handled on screen.
It is also not clear whether the injury will be written into Buck’s storyline or concealed through production techniques.
Those details may become clearer once the new episodes begin airing.
When does 9-1-1 Season 10 premiere?
9-1-1 Season 10 is scheduled to premiere on ABC on Thursday, October 15, 2026, at 8 p.m. Eastern and 7 p.m. Central.
The series will also be available to stream through Hulu in the United States.
ABC’s official listing identifies the new season and promotes Stark’s return as Buck alongside Angela Bassett, Jennifer Love Hewitt, Kenneth Choi, Aisha Hinds and Ryan Guzman.
The premiere will arrive as questions remain about the production’s stunt practices and the extent to which recent injuries could affect future filming.
What happens next
Stark has reportedly resumed work, but no public medical update from the actor has been released in connection with the ankle injury.
The production also has not publicly detailed whether additional safety procedures will be introduced for the remainder of the season.
For viewers, the immediate next step is the Season 10 premiere, which will show whether Buck’s physical condition is reflected in the story.
The reported injuries also highlight the difference between the danger portrayed by first-responder dramas and the real safety coordination required to stage those scenes.
