Gibbons' spokesman Dan Burns on Tuesday said doctors have not said when the 65-year-old governor will be released, or where he will go after that.
Burns says Gibbons is alert and has started some limited therapy at the hospital, but remains in considerable pain. He says senior staff has been briefing him daily on state issues.
Gibbons was bucked off the horse Sept. 21 at a private ranch about 45 miles north of Reno.
Gibbons' pelvis was broken in two places, and doctors used four large screws to repair the damage.
