Abrams, however, assured fans that the actor was doing fine.
"He sends his best, and he's doing great and working hard. I had respect for him all my life, but I've never had more respect for a guy until I saw how he landed that plane - that was an amazing thing that he did. He's more of a hero in that move than I think he's been in all the movies he's been in. That was an incredible thing to do," Abrams said.
"The amazing thing about Harrison... Is that he's the only person that can make an emergency landing on a golf course in front of two doctors.
"So he's home and resting and getting well as fast as he can. I can't even begin to tell you how much he wanted to be here... But by the time we open this movie, I know that Han Solo will be very actively involved in what we're doing," she said.
