Jeremy Renner suffered 'blunt chest trauma and orthopaedic injuries' in accident

Actor Jeremy Renner suffered "blunt chest trauma and orthopaedic injuries" after a New Year's Day snow ploughing accident, a spokesperson for the Marvel star says.

Renner, 51, had surgery on Monday and "remains in the intensive care unit in critical but stable condition", the spokesperson said.

He was hospitalised in critical condition after being injured in the US state of Nevada.

"Jeremy's family would like to express their gratitude to the incredible doctors and nurses looking after him, Truckee Meadows Fire and Rescue, Washoe County Sheriff, Reno City Mayor Hillary Schieve and the Carano and Murdock families," a statement from his spokesperson read.

"They are also tremendously overwhelmed and appreciative of the outpouring of love and support from his fans."

The Hawkeye actor has so far required two surgeries to address injuries he sustained in the accident, a source close to the actor previously told CNN.

"His injuries are extensive," they said.

Officers responded to a "traumatic injury" in the area of Mount Rose Highway in Reno, according to a news release from the Washoe County Sheriff's Office, which has previously said the Academy Award-nominated actor lived in the community.

A neighbour told TMZ the plough, a Snowcat, accidentally ran over one of the actor's legs, leading to major blood loss.

Another neighbour, reportedly a doctor, put a tourniquet on Renner's leg until the arrival of paramedics.

Deputies coordinated with Truckee Meadows Fire Protection District and REMSA Health to arrange for medical transport of Renner via care flight to a local area hospital, the release stated.

Renner, who stars in the series Mayor of Kingstown and has been featured in several Marvel Cinematic Universe films - including in the role of Hawkeye - was the only person involved in the accident, officials said.

Renner has featured multiple videos and photos on his verified social media accounts showing him in snowy conditions.

"How would you feel if your driveway looked like this??" his caption reads.

In one video posted two weeks ago and featured in his Instagram holiday highlights reels, Renner appears to be driving a snow plough with the caption, "pave new paths, holiday adventures".

Another from a week ago shows snow being ploughed with the caption, "Nearly done with sledding hill for the kids."

Renner is a two-time acting Oscar nominee, scoring back-to-back nods for The Hurt Locker and The Town.

Renner's portrayal of a bomb disposal specialist in Iraq in 2008's The Hurt Locker helped turn him into a household name.

The Avengers in 2012 cemented him as part of Marvel's grand storytelling ambitions, with his character appearing in several sequels and getting its own Disney+ series, Hawkeye.
