His chief of staff said that no one knows yet when the Democrat will be able to return to work, The Star-Ledger of Newark reported. Corzine, who was not wearing a seat belt, suffered more than a dozen fractures in the crash.
At an afternoon news conference with Corzine's chief of staff, Tom Shea, Senate President Richard Codey, who is serving as acting governor, promised to make no major changes while Corzine is incapacitated. Codey and Shea said that Corzine might be able to work from his home or even a hospital during his recovery.
"It's their administration, not mine," Codey said.
Codey served as acting governor for more than a year after Gov. James McGreevey resigned in 2005.
Corzine suffered 12 broken ribs and a broken lower backbone, breastbone, collarbone and femur. He had a breathing tube because he is so heavily sedated.
Dr. Steven Ross, head of the trauma unit at Cooper, said Corzine is able to signal yes or no answers to questions.
A staff member and a state trooper suffered minor injuries in the crash.
