The veteran actor, 71, sustained a broken leg in early June when the door of the Millennium Falcon spacecraft fell on top of him while shooting at Pinewood Studios in the UK.
He underwent surgery and was recently photographed back on his feet with the help of a special supportive crutch, less than three weeks after the accident.
Filming continued in Ford's absence, but now Disney studio executives have decided to halt production for a fortnight next month to allow Abrams to rework the shooting schedule.
However, Disney bosses insist Star Wars: Episode VII is still "on track" to wrap this autumn and will be in cinemas for its planned December, 2015 release date.
Meanwhile, Abrams has added two new castmembers to the film - acting newcomers Crystal Clarke and Pip Anderson - although details about their roles are being kept under wraps.
They join the likes of Irish actor Domhnall Gleeson, Adam Driver, Oscar Isaac, Lupita Nyong'o, Andy Serkis and original franchise stars Carrie Fisher and Mark Hamill in Episode VII.
