RUSTON, La. (AP) -- Louisiana Tech running back Tyrone Duplessis has been found dead at his off-campus apartment.

Hazel Woods, the chief investigator for the Lincoln Parish coroner's office, says the cause of death is not yet known and an autopsy is pending.

The 21-year-old Duplessis, whose body was found Thursday morning, recently completed his sophomore season of eligibility. Louisiana Tech spokesman Patrick Walsh says coach Sonny Dykes has informed the team, which was expected to have a meeting later Thursday. The university has also made grief counselors available to the team.

Duplessis, who is from New Orleans, played in two games last season as he sought to come back from a knee injury that sidelined him in 2010. As a true freshman in 2009, he had 70 carries for 277 yards.
