Deadline reports that four performers, including star Oliver Stark, sustained stunt-related injuries to varying degrees in recent months while filming Season 10 of ABC's '9-1-1.' In late August, Stark — who plays Evan 'Buck' Buckley — broke his ankle during a stunt and required surgery; sources close to production say he has since returned to work. The stunt involved a firefighter swinging from a car over a set piece to the ladder truck. According to Deadline, a stunt double sprained an ankle rehearsing the same maneuver and declined medical treatment, so no injury report was submitted to production. The stunt's mechanics were adjusted after the double's injury, but sources indicate Stark still rolled his ankle over another performer. A spokesperson for 20th Television declined to comment.

Per Deadline, two other injuries followed in subsequent weeks. In one, a stunt person injured their arm on a piece of the set with jagged metal on it, requiring a hospital visit and stitches. Within the last two weeks, another stunt performer was sent to the hospital after what sources called a 'precautionary' trip following an 'awkward landing' on a platform designed to simulate a ground collapse; the landing resulted in a broken rib and minor compressed lung. Deadline reports it is unclear whether that performer has returned to work. Page Six, citing Deadline, reported the same sequence of incidents, noting the alleged injuries occurred 'to varying degrees in recent months' and that the incidents 'do not seem to be connected' to one another.

A cluster of injuries on a single season does not necessarily indicate negligence — Deadline itself cautions that a high-octane show like '9-1-1' carries inherent risk. But the outlet notes it is ambitious for a broadcast series to stage massive stunt sequences on a regular basis given the relatively tight production schedule network shows require, making problems more likely to occur. The shadow of an earlier tragedy looms: Deadline previously reported that two years ago a crew member died from a cardiac event while driving home after a workday ballooned to 14 hours amid complications with a controlled burn used for a stunt. Page Six adds that per an autopsy report, grip Rico Priem experienced 'sudden cardiac dysfunction due to cardiomegaly' after leaving set at 4 a.m. — yet a production source told Deadline at the time the show was 'one of the safest that I've ever worked on.'

All SAG-AFTRA signatories, including Disney, which owns 20th Television, must follow on-set safety protocols. Per Deadline, stunt performers and coordinators must complete a general safety and injury prevention program to stay eligible for union productions, with standards developed by Contract Services' industry-wide safety committee. The latest stunt safety bulletin tasks production management with ensuring enough time for 'rehearsals, training, equipment preparations, and inspections.' The stunt coordinator leads preparations from script review through rehearsal, and the first assistant director must hold an on-set safety meeting before any stunt work, with another required after any 'substantive changes.' Sources told Deadline that '9-1-1' typically rehearses stunts first with heavyweight bags before doubles, then actors. Stark has not publicly discussed the reported injury and surgery, per Yahoo/In Touch Weekly.

Yahoo, carrying In Touch Weekly, notes Stark has previously spoken about how demanding the show's action sequences are, recalling the season 6 finale in which Buck repelled back and forth to move people from a collapsed highway to an ambulance. 'I was pretty bruised and battered and exhausted by the end of the day, but also felt very accomplished,' he told The Wrap, adding that physical set pieces are where he 'thrives.' The new injuries land as Season 10 approaches its Oct. 15 premiere, with showrunner Tim Minear telling TV Insider that Buck's fostering journey with Eddie (Ryan Guzman) will be 'heartwarming and very hard.' Production on the season continued after Stark's injury, and no pause has been reported.

Deadline's exclusive has already circulated across Page Six, Yahoo and Hiru News within a day, and attention will likely stay on the show's safety record as Season 10 airs. A rep for ABC did not immediately respond to Page Six's request for comment, and 20th Television declined to comment to Deadline — so there is no studio statement on whether protocols will change. The reported incidents arrive amid a broader moment for stunt-safety headlines: Page Six notes Kate Beckinsale's ongoing 2025 lawsuit over alleged 'dangerous and unsafe conditions' on 'Canary Black.'
