HOUSTON (AP) — Houston cornerback D.J. Hayden remains 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 Tuesday to Memorial Hermann Hospital. 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 kind of injury is fatal "95 percent" of the time and is associated with high-speed car accidents.

Hayden leads Conference USA with four interceptions. He had returns for touchdowns in consecutive games against SMU and UTEP earlier this season.
