Former Olympic swimmer Amy Van Dyken is in intensive care at an Arizona hospital -- after suffering serious injuries in an ATV crash.
The 41-year-old -- who's married to former Denver Broncos punter Tom Rouen -- was riding in Show Low, AZ on Friday when she crashed.
Amy's sister posted a message on Facebook saying she was airlifted to a hospital in Scottsdale. She is currently being treated in the intensive care unit, according to AZcentral.com.
Van Dyken is a national hero -- who won gold medals at the '96 and 2000 games.
