Marion Barber was found dead at his home in Frisco, Texas, on Wednesday, according to the Fort Worth Star-Telegram. Frisco police discovered Barber, and the cause of his death is not yet known.
The former 109th pick of the 2005 NFL Draft was just nine days away from his 39th birthday.
Barber came out of Plymouth, Minnesota, and played college ball at the University of Minnesota before getting picked by the Dallas Cowboys. Barber ran for 538 yards and five touchdowns in his rookie campaign with Dallas.
He followed up his freshman season with 24 touchdowns on the ground in the next two seasons and was named to the Pro Bowl for his solid 2007.
