Former England cricketer Andrew Flintoff will explore mental illness in sport for a new BBC documentary.
Flintoff will investigate various players' experiences with depression in The Dark Side of Sport, reports The Sun.
The BBC said that the 34-year-old has "first-hand experience of watching sporting colleagues battle privately with the illness throughout their careers".
Rugby player John Kirwan, Celtic manager Neil Lennon and boxer Frank Bruno are among the stars who have spoken about their battles with the illness.
Flintoff's England teammate Marcus Trescothick retired after depression forced him to pull out of two tours. Speaking recently, he admitted that he is still determined to beat "the beast" which "takes over" him.
BBC commissioning editor Charlotte Moore said: "Depression is a subject we avoid talking about, particularly in sport, where it is increasingly prevalent."
Flintoff previously appeared in ITV4 series Freddie Flintoff Versus the World and as a team captain on Sky1 panel show A League of Their Own.
