The actor, who is reprising his role as Han Solo in the new film, broke his leg during a freak accident at Pinewood Studios last month.
Harrison was airlifted to hospital when a hydraulic door collapsed on him during filming.
It was initially thought that the star would be out of action for eight weeks and while the timescale still looks accurate, production on the movie has come to a complete standstill, according to The Mirror.
“Harrison is so integral to the film it’s now being shot around his recovery,” a source told the paper.
Peter Mayhew will also reprise his role as Chewbacca, while Carrie Fisher, Anthony Daniels and Kenny Baker are also among those returning.
