Warriors all-time great Nate Thurmond passed away at age 74.

The Golden State Warriors announced on Twitter early Saturday afternoon that Nate Thurmond passed away at the age of 74 after battling leukemia.

Thurmond was selected third overall in the 1963 draft out of Bowling Green State University, and would go one to spend 14 seasons in the NBA, 11 of which were spent with the Warriors franchise. All seven of his All-Star selections came when he was with either San Francisco or Golden State, and he averaged 17.4 points and 16.9 rebounds during his time in Northern California.

Arguably, his best season came in 1967-68 when he averaged 20.5 points and 22.0 rebounds per game for a Warriors team that went 43-39. He still holds the Warriors’ franchise records in minutes played (30,735) and total rebounds (12,771).

He was elected to the Hall of Fame in 1985 and boasts an impressive list of accolades. To start, Thurmond was the first player ever to tally a quadruple-double when he amassed 22 points, 14 boards, 13 assists, and 12 blocks against the Atlanta Hawks in 1974. He’s also one of the greatest rebounders ever to play. For his career, Thurmond averaged 15.0 rebounds a game and joined Wilt Chamberlain, Bill Russell, Bob Pettit, and Jerry Lucas as the one players to do so, according to Basketball-Reference.

Honored as one of the 50 Greatest Players in NBA History, Thurmond spent three decades working the Warriors after he retired from playing. The organization retired his #42 jersey in March of 1978.
