(CNN) South Carolina congressional candidate Katie Arrington is in the hospital with serious injuries after being involved in a fatal car wreck Friday night.

Arrington was traveling on a highway in the passenger seat when another driver traveling in the wrong direction struck the car carrying her and a friend, her campaign said on Twitter. She and her friend were driving to Hilton Head, where Arrington was scheduled to receive an award Saturday morning, her campaign said.

According to her campaign, Arrington suffered a fracture to her back, broken ribs, and a partial collapse of the main artery in her legs. She will have to undergo "major surgery" to remove a portion of her small intestine and a portion of her colon, and will require a stent in the main artery in her legs.

Her spokesperson Michael Mule said Saturday morning that Arrington was alert and recovering in the Medical University of South Carolina hospital. Her family was with her at the hospital, Mule said.

Her campaign said later Saturday that Arrington "remains in critical but stable condition" and is scheduled for "another major surgical procedure" Sunday morning.
