Natasha Richardson Skiing-Accident Details Emerge

Actress reportedly showed no signs of trauma after falling during a ski lesson Monday.

A day after award-winning actress Natasha Richardson was hospitalized in serious condition following a skiing accident in Canada, more details have emerged on how the actress was hurt.

According to CNN, Richardson — who was transferred on Tuesday (March 17) to an undisclosed location in the United States after receiving treatment at a Montreal, Quebec, hospital — fell on a beginners' ski trail Monday during a lesson at the Station Mont Tremblant resort.

The actress was accompanied by a ski instructor at the time of her fall, and that person called the ski patrol, according to a statement released by the resort. "She did not show any visible sign of injury, but the ski patrol followed strict procedures and brought her back to the bottom of the slope and insisted she should see a doctor," the statement reads.

The instructor accompanied Richardson, 45, back to her hotel, but about an hour after the fall, she reported "not feeling good," according to the statement, and an ambulance was called. She was taken to a local hospital and then transferred to Hôpital du Sacré-Coeur de Montréal, where she appears to have spent the night. The statement did not offer any details on Richardson's condition or injuries, though People has reported that she is in serious condition with head trauma.

A spokesperson from the resort told People that Richardson, known for her award-winning stage work and movie roles in "The Parent Trap" and "Nell," was "laughing and joking, and she walked to her room on her own" following the fall. The magazine also reported that Richardson was not wearing a helmet during the lesson. The spokesperson said Richardson did not hit anything or anyone before coming to a stop and that there were no cuts, bleeding or other external signs of injury.

On Tuesday afternoon, TMZ reported that an unidentified hospital source said Richardson was sedated and suffering from brain swelling.

Richardson is married to actor Liam Neeson, who reportedly flew to be by her side from the Toronto set of his current project, "Chloe."
