Survivor favourite Ralph Kiser has died of a heart attack at the age of 56, his family have announced.
The Virginia native, who competed in season 22 in 2011, is said to have passed away suddenly on Wednesday morning.
Show host Jeff Probst tweeted: "The Survivor family extends our deepest condolences to the family of Ralph Kiser.
"His huge smile, his positive attitude and of course his infectious rooster crow made him one of the most likable to ever play Survivor. We are all so sorry for your loss."
Podcast host Mike Bloom wrote: "It's tough to dim the lights on #Survivor day, but it seems that the alumni family has lost another member today: Ralph Kiser from Redemption Island.
"R.I.P. to one of the few lights in a very dark season, who provided 33 days of accidental idol finding, rooster crowing & more."
Kiser placed eighth in his season, which was won by franchise regular Boston Rob.
