"It is with a heavy heart we announce the passing of our father, Doyle Brunson," the statement read. "He was a beloved Christian man, husband, father and grandfather. We’ll have more to say over the coming days as we honor his legacy. Please keep Doyle and our family in your prayers. May he rest in peace."

Brunson was known as the "Godfather of Poker" and "Texas Dolly" during his heyday. His World Series of Poker wins are only second to Phil Helmuth’s 16 championships. He also captured world championships in 1976 and 1977 and was inducted into the Poker Hall of Fame in 1988.

He was the first to win $1 million in poker tournaments. In his final tournament in 2018, he made the final table and finished in sixth place.
