In court papers, Sanderson said he suffered "permanent traumatic brain injury" as a result of the collision.
Paltrow said that is when they both fell to the ground with Paltrow on top of Sanderson, in a heap of skis and limbs.
Gwyneth Paltrow testifies during her ski crash trial, in Park City, Utah, U.S., March 24, 2023.
Paltrow, who said she was upset and cursed at Sanderson after the collision, said she did not ski off until after Sanderson told Christiansen that he was fine.
"I did not cause the accident, so I cannot be at fault for anything that subsequently happened to him," Paltrow said.
