Celtics Hall of Famer and eight-time NBA champion John Havlicek died Thursday at the age of 79, the team announced.
"John was kind and considerate, humble and gracious," the team wrote in a statement. "He was a champion in every sense, and as we join his family, friends, and fans in mourning his loss, we are thankful for all the joy and inspiration he brought to us."
Havlicek was diagnosed with Parkinson's Disease in his later years but no immediate cause of death has been released.
He was drafted out of Ohio State in 1962 after spending his college years playing alongside coaching icon Bobby Knight.
The Buckeyes won the national championship in 1960.
One of the most prolific "sixth men" in NBA history, Havlicek played alongside former NBA coach Don Nelson in Boston and Hall of Famer Bill Russell.
The long-time guard/forward for Boston was named to 13 All-Star teams and another 11 All-NBA rosters.
He was part of a Celtics team that won four straight titles from 1963 to 1967.
He ultimately won eight championships with Boston.
Havlicek averaged 20.8 points, 6.3 rebounds and 4.8 assists in his career.
