"Fast & Furious 9" stuntman Joe Watts is in a medically induced coma following a serious head injury Monday, a person familiar with the situation but not authorized to speak publicly tells USA TODAY.

Watts was on an elevated stage which was part of an action sequence, according to the source. The mishap shut down the action film's production on the Warner Bros. set in Leavesden, England, about 20 miles northwest of London.

Police and ambulance services were called and Watts was evacuated by air ambulance after the incident, which comes less than a week after the death of a crew member on TV's "Titans" series during stunt preparation in Toronto.

Watts is an experienced stunt performer with work on "Game of Thrones," "Star Wars: The Last Jedi" "Mission: Impossible – Fallout" and "Kingsman: The Golden Circle."

Speaking at the London premiere of "Fast & Furious Presents: Hobbs & Shaw," Jason Statham called the incident in the franchise-related movie "absolutely awful news. We just wish him the best."

"It's a very concerning thing when someone gets hurt," said Statham. "The families have to endure that.difficulty."

Britain's The Sun referred to the mishap as a 30-foot "horror fall." Hetrfordshire Police told the paper: "Police were called shortly before noon today following an incident at Warner Bros. Studios in Leavesden, Hertfordshire. It was reported that a man had been injured while working at the location and sustained serious injuries."

The stunt was part of a smaller second unit of filming. "Fast & Furious 9" filming began again Tuesday.

"Fast & Furious 9" features the franchise cast of Vin Diesel, Michelle Rodriguez, Tyrese Gibson and Ludacris, along with returning cast members Helen Mirren and Charlize Theron.

The "Fast & Furious" franchise has been marred by tragedy previously. In November 2013, franchise star Paul Walker was killed when a Porsche Carrera GT being driven at high speed by his friend Roger Rodas spun out of control, crashed and burst into flames, killing them both.
