Don Nelson, a five-time NBA champion and one of the winningest head coaches in league history, died Sunday at the age of 86, his family announced in a statement.

Nelson won five NBA championships with the Boston Celtics between 1965 and 1976 during a 14-season playing career that also included stints with the Chicago Zephyrs and Los Angeles Lakers.

Don Nelson became one of the NBA's winningest coaches

After his playing career ended, Nelson went on to build an extensive résumé as an NBA head coach.

Over 31 seasons, he coached the Milwaukee Bucks, Golden State Warriors, New York Knicks and Dallas Mavericks.

Nelson finished his coaching career with a 1,335-1,063 record, establishing himself as one of the winningest head coaches in NBA history.

His 1,335 career wins were eventually surpassed only by Gregg Popovich, who reached 1,390 victories.

Nelson was also named NBA Coach of the Year three times, adding another distinction to a coaching career that spanned more than three decades.

In 2012, Nelson was inducted into the Basketball Hall of Fame, cementing a legacy that included five championships as a player and 1,335 wins as a head coach.
