Ferguson will be buried in Bains, Louisiana, where he was born.
Ferguson appeared to have worked hard to be in the best shape of his career, dropping a significant amount of weight. During the team's off-season workouts this spring, he was playing a bigger role on defense, while the starting outside linebackers were recovering from surgeries.
Ferguson is known as "Sack Daddy" due to his 45 career sacks. He made 67 tackles and 4.5 sacks in three seasons in the National Football League.
Three of Ferguson's children are under the age of five.
Many of the children's belongings were lost in a house fire, but Ferguson and his family were able to survive. He tried to put out the fire in order to save his children's possessions, but he burned his own toes in the process.
