PHILADELPHIA -- Hal Greer, a Hall of Fame guard and the Philadelphia 76ers' career leading scorer, has died after a brief illness, the team announced. He was 81.

Greer starred on the Wilt Chamberlain-led Sixers team that went 68-13 and won the 1966-67 NBA championship.

During the Sixers' 1966-67 title run, Greer averaged a team-high 27.7 points over 15 playoff games and helped Philadelphia dethrone the reigning eight-year champion Boston Celtics.

The Sixers honored Greer before their playoff game against the Miami Heat on Monday night with a moment of silence. They are wearing a patch on their uniforms with Greer's No. 15. He was the first Sixer to have his number retired.
