Fox has announced that the third movie in the "Maze Runner" trilogy has been delayed from its February 2017 release, reported Variety.
It comes as O'Brien recovers from injuries after a "very serious" on-set car accident on March 18.
Production was shut down indefinitely after a prop car reportedly struck the actor, and it is unclear when it will resume again.
The second film in the trilogy, "The Scorch Trails", was released last year, following the first movie in 2014.
