Houston cornerback D.J. Hayden remains hospitalized in "stable, yet critical" condition after tearing a vein during a collision with a teammate during practice.
Team physician Dr. Walter Lowe said in a statement from the school Thursday that the senior was taken by ambulance after the Tuesday collision to Memorial Hermann Hospital, where he had immediate surgery for a tear of the inferior vena cava, the large vein that carries blood from the lower half of the body to the heart.
Lowe says that type of injury is fatal "95 percent" of the time. He says such an injury is associated with high speed motor vehicle accidents.
Hayden leads Conference USA with four interceptions and had returns for touchdowns in consecutive games against SMU and UTEP earlier this season.
