She has been in an induced coma since Saturday, September 5, suffering from head injuries and a punctured lung, reported Ace Showbiz.
Jackson was filming a chase scene when the tragedy happened. She rode a motorcycle at high speed and suddenly crashed into a piece of metal camera arm. Unfortunately, she wasn't equipped with any protective gear or helmet during filming.
A source close to the production said, "It wasn't a very dangerous stunt. She was riding a motorbike in a straight line but due to the scene she had no protective gear or helmet. There is a metal arm which carries the camera along. But it malfunctioned and didn't lift up.
Her husband, David R Grant, rushed from filming in Malta to be at his wife's side. He then posted a photo of himself and Jackson on Facebook while also telling people that she had "been making steady progress."
