New York (CNN) -- The Broadway actor who fell more than 20 feet while performing a stunt in the "Spider-Man" musical was discharged from Bellevue Hospital, his father Tim Tierney told CNN Wednesday.
Christopher Tierney, 31, was moved into a rehabilitation center after leaving the hospital's intensive care unit Tuesday night, he said.
The actor suffered four broken ribs, a hairline fracture in his skull, a broken scapula, a bruised lung, three cracked vertebrae and broken bones below his elbow, his father said.
"Spider-Man: Turn Off The Dark" returned Thursday after several shows were canceled because of the injury and subsequent safety reviews.
Jonathan Dealwis, a tourist from New Zealand who was in the audience that night, said he saw Tierney fall.
"Spider-Man was on a bridge, and Mary Jane was dangling from it," Dealwis said. "I think he was meant to sort of swoop over there, but he just fell off.... The harness, you could see it just flick off his back and fly backward."
Workers for the show met with the Occupational Safety and Health Administration and the New York State Department of Labor and devised new safety rules for the show.
