Former professional golfer and television host David Feherty announced on Tuesday his son died from a drug overdose on his 29th birthday.

"My first born son is gone from me, dying from an overdose on his 29th birthday. Bless his sweet heart, I will fight on," Feherty said.

Fans and celebrities, including Don Cheadle, Kevin Burkhardt and Ron Mintz sent Feherty their condolences.

"Oh, David. Gutted. No words. Thinking of you and love you, man," Cheadle wrote.

"Prayers David. Thinking of you," Kevin Burkhardt said.

The Golf Channel, where Feherty's talk show airs, also said in a statement: "Our deepest condolences go out to David Feherty and his family on the passing of his oldest son, Shey. Family means everything to David, and his Golf Channel, NBC Sports and extended television family send their love and support at this difficult time."
