Jeremy Renner celebrated his 52nd birthday in the hospital while recovering from injuries sustained when he was hit by a snow plow.

The “Avengers” star, who has been in intensive care since his January 1 accident, was running to help a family member who was stranded in the snow on his Lake Tahoe property when he was hit by a seven-ton snow plow.

He was deemed to be in critical condition following the accident and required two surgeries, including the implantation of metal pins around his leg.

However, he was awake and able to communicate as of this week. He even posted a photo of himself in a hospital bed with visible facial bruising, thanking well-wishers for their kind words.

According to a source who spoke with Radar Online, the “Bourne Legacy” actor’s friends are now concerned and fearful that he will become permanently disabled.

“Jeremy has already undergone two complex operations. But there are significant questions about whether he will ever be able to walk correctly, or at all.

His loved ones are concerned that, if he doesn’t completely lose the limb, the injury is severe enough to prohibit him from moving the way he used to.

Jeremy could need surgically inserted rods to help his legs recover, but Dr. Gabe Mirkin, who isn’t treating the actor for his injuries, cautioned that he might also have to undergo an amputation and use an artificial leg.”

The medical expert added:

“This will be a long and slow recovery for him.”

According to police, Jeremy Renner attempted to use his 14,330-pound snow plow to assist in the rescue of a family member who had become stranded in the snow in a personal vehicle.

Sheriff Darin Balaam claimed that the snow plow began to move as soon as he stepped out of the car to speak with the unnamed family member. When Jeremy attempted to re-enter the car, he was hit by it.

According to a 911 call made after the incident, the actor’s upper body was crushed and the right side of his chest collapsed. In a call obtained by TMZ, the Hollywood A-lister could be heard wailing and bleeding heavily from his head and other injuries.

Jeremy Renner struggled to breathe before being airlifted from the scene of the accident to a nearby hospital due to his injuries.
