George Huguely, 22 of Chevy Chase, Md., was charged with first-degree murder and jailed in Charlottesville, Va.
He was arrested after the body of Yeardley Love, 22 of Cockeysville, Md., was found early Monday at an off-campus apartment. Police her body showed signs of physical trauma, although a determination of the cause of death was pending an autopsy.
Investigators said they were told Huguely and Love, both seniors, had a previous relationship.
The university issued a statement, saying in part, "this death moves us to deep anguish for the loss of a student of uncommon talent and promise and we express the university's and our own sympathy for Yeardley's family, teammates, and friends."
Huguely, a midfielder, had appeared in all of Virginia's 15 games this season, scoring four goals and assisting on three others. The Cavaliers men's team is 14-1 this season.
Love, a defender, had played in 15 of her team's 18 games, starting three.
