Production on the new Gabrielle Union series, L.A.’s Finest, has temporarily been shut down following the showrunners, Brandon Sonnier and Brandon Margolis, being injured on set.

Both men suffered serious but nonlife-threatening injuries last Thursday when a stunt car crashed into a cargo crate, which then smashed into the area where they were standing off-camera, ET reports. Both executives were rushed to the hospital, and Margolis has since been released. Sonnier has been transferred to another facility and is still in recovery.

Deadline reports The California Occupational Safety and Health Administration (OSHA) has opened an investigation into Mesquite Productions, a company under Sony Pictures Television.

L.A.’s Finest, starring Union and Jessica Alba, was in its final days of shooting its first season when the accident occurred. The Spectrum series was due to premiere May 13, but that date will likely be changed due to the production shutdown.
