Zahn McClarnon, a recurring actor on the second season of “Westworld,” has been hospitalized due to an off-set injury, pausing production on the HBO drama.

HBO confirmed the news on Friday afternoon, saying in a statement, “Actor Zahn McClarnon was hospitalized Wednesday night after sustaining an injury at home. He is on the mend and looking forward to getting back to work. ‘Westworld’ will resume filming on both units next week.”

According to TMZ, which first broke the news, McClarnon fell and hit his head at home. He was reportedly rushed to the ICU with brain trauma. Variety has reached out to McClarnon’s camp for comment.

News broke on Thursday, when HBO announced that production on Season 2 had been halted due to a cast injury, but would not reveal any names at that time.

“Due to a medical emergency involving a performer in a recurring role on season 2 of ‘Westworld,’ filming on one of the two units has been temporarily suspended,” HBO said on Thursday. “The cast member was not on set when this occurred, and out of respect for the performer’s privacy, we have no additional details to share, other than that everyone at ‘Westworld’ sincerely hopes for a quick recovery.”

McClarnon also appears in AMC’s “The Son” as Toshaway, as well as Netflix’s “Longmire,” which debuts its final season on Nov. 17. His other TV credits include the second season of FX’s “Fargo,” where he played Hanzee Dent; SundanceTV series “The Red Road”; and one episode of NBC’s “Timeless.”
