The movie star was airlifted to a hospital in Oxford, England, last week after the accident. His son Ben told TV show "Access Hollywood" his father may need screws and a plate fitted to aid his recovery.
Other sources tell The Hollywood Reporter that Ford will miss as many as eight weeks of filming due to his injury.
A source tells the publication that the actor, who reprises his role as Han Solo in the Star Wars sequel, was injured by the door of the Millennium Falcon, the spacecraft that his character pilots in the original films.
