Christopher Reeve was thrown from his steed during a horse-jumping competition and was in stable condition on Sunday.

The actor who starred in the “Superman” movies was admitted to the University of Virginia Medical Center in Charlottesville after the accident on Saturday, said his publicist, Lisa Kasteler.

Reeve, 42, was approaching the third jump of a 15-jump course when “something spooked the horse,” said Monk Reynolds, owner of Commonwealth Park in Culpeper, about 45 miles northeast of Charlottesville.

“His horse just stopped dead and threw him,” said Reynolds.

He said Reeve appeared to suffer a neck injury and was carried off the field in a stretcher.
