The 51-year-old star suffered serious injuries Sunday morning near his Nevada home trying to stop the PistenBully machine, which had started rolling forward after he used it to help free a stranded family member’s vehicle from heavy snowfall.
Renner, who was airlifted to Reno, posted a selfies Tuesday from his hospital bed, showing heavy bruising on his face.
“Thank you all for your kind words. I’m too upset to write now. But I’m sending love to you all,” Renner wrote on Instagram.
Renner’s publicist, Sam Mast, said the actor had undergone surgery and was “progressing positively and is awake, talking and in a good mood.”
“He remains in the ICU in critical but stable condition,” Mast said.
Local authorities said at a news conference on Tuesday that there were no indications that alcohol or drugs were involved in the incident, which was being treated as a “tragic accident.”
According to Washoe County Sheriff Darin Balaam, an investigation was underway into Renner’s “serious injuries,” including checks for any signs of mechanical failure.
The actor was using a PistenBully, or snowcat, a track-drawn vehicle the size of a truck designed to remove snow.
Renner was nominated for two Oscars for his roles in “The Hurt Locker” (“Living on the edge” or “In hostile land”) and “The Town” (“City of thieves” or “Dangerous attraction”).
