Louisiana Tech running back Tyrone Duplessis was campus apartment on Thursday morning.

The 21-year-old was in his third year at Louisiana Tech.

The cause of death is not yet known and an autopsy is pending.

"Tyrone was a valuable part of this football family," head coach Sonny Dykes said. "This is a tragic, senseless loss, but he made a lasting impact on this team, University and everyone that knew him."

Duplessis ran the ball just seven times this season as he recovered from a knee injury sustained during the 2010 season.

He is survived by his parents, George and Mary, and two siblings, George III and Levoneshia Dixon.
