DENVER (AP) — Olympic champion swimmer Amy Van Dyken-Rouen plans to undergo rehabilitation for her severed spine at a suburban Denver hospital.

Van Dyken-Rouen plans to be transferred sometime next week to Craig Hospital, which specializes in spinal cord injuries. Her husband, former Denver Broncos punter Tom Rouen, told The Denver Post (http://bit.ly/1loXCy7 ) that she may still need to undergo a second surgery at the Scottsdale, Arizona, hospital where she has been since she was injured in an all-terrain vehicle crash Friday night.

Tom Rouen says the family doesn't know if she will be paralyzed, saying "we're going to take it day by day."

Van Dyken-Rouen remains upbeat in her Twitter posts. On Thursday morning, after spending most of the night undergoing an MRI, she joked "Yes, I have a brain!"
