Saget, well known for his role in the famous 1980s-1990s sitcom Full House, was discovered comatose in the Ritz Carlton in Orlando while on tour, and the cause of death was previously unclear.
“The authorities have determined that Bob passed away from head trauma,” his relatives said in a statement.
“They have concluded that he accidentally hit the back of his head on something, thought nothing of it and went to sleep,” they added, noting that “no drugs or alcohol were involved.”
Saget soared to fame in his Full House role as Danny Tanner, a widowed father of three girls, including a daughter played alternately by twin sisters Mary-Kate and Ashley Olsen.
After his death, the Olsens paid tribute to Saget as “the most loving, compassionate, and generous man.”
He was also an accomplished stand-up comedian, lent his voice as narrator on the CBS series How I Met Your Mother, hosted America’s Funniest Home Videos in its early years, and appeared numerous times playing himself on HBO’s Entourage from 2005 to 2010.
