The Arizona Department of Public Safety said Monday two of its personnel were among those injured in the shooting in Las Vegas Sunday night.
According to DPS, a trooper was hit with shrapnel while another employee had some bumps and scrapes.
Both have been released from the hospital.
A gunman had opened fire from his 32nd-floor room at the Mandalay Bay Resort and Casino as Jason Aldean performed below.
Officials said the gunman, identified as 64-year-old Stephen Paddock, was found dead in his room, but not before killing at least 58 and wounding 515 more. It's the deadliest mass shooting in modern U.S. history.
