Maze Runner star Dylan O'Brien's injuries are much more severe than first thought.

Maze Runner star Dylan O’Brien‘s injuries from an accident on set back in March are said to be worse than first thought, with production on the film pushed back indefinitely.

The announcement comes after O’Brien’s publicist told the media that her client’s injuries are worst than first anticipated.

“His injuries are very serious, and he needs more time to recover,” she said.

The 24-year-old was  in Vancouver, Canada, on March 18 when sources reported that he fell from the back of a train on set and was run over by a car.

Initially, production was set to return on May 9, with Fox believing that timeline was suitable in conjunction with the seriousness of the 24-year-old’s injuries. At this stage, production has been shut down”for the foreseeable future”, with cast and crew given an extended period off.

The Fox project was slated for release on Feb, 17, 2017, but for obvious reasons this date will now be pushed back.

Fox Studios have released a statement today acknowledging the severity of O’Brien’s injuries and their desire to give him a greater timeline to recover.

“The resumption of principal photography on The Maze Runner: The Death Cure has been further delayed to allow Dylan O’Brien more time to fully recover from his injuries. We wish Dylan a speedy recovery and look forward to restarting production as soon as possible,” it read.

‘The Death Cure’ is the third instalment in ‘The Maze Runner’ franchise, with O’Brien playing the film’s protagonist, Thomas.
