​Today is a sad day in the world of basketball, as seven-time NBA Champion and Basketball Hall of Fame inductee Frank Ramsey has passed away.

Ramsey would have turned 87 years old on July 13. The cause of his death has not been released to the public.

Ramsey started his professional basketball career as a shooting guard for the ​Kentucky Wildcats. While he was on the roster, the Wildcats went all the way in the 1951 NCAA Tournament.

In his time with Kentucky, Ramsey recorded 1,038 rebounds, which is the second highest mark in the history of the university, even though he was only 6-foot-3. He's also in the top 30 in career points for the Wildcats with 1,344.

Ramsey was drafted in the first round by the ​Boston Celtics in 1953 and over the course of his career averaged 13.4 points per game. Legendary coach Red Auerbach made Ramsey the first ever sixth man for a franchise that would breed several greats, including Bill Russell, John Havlicek and Kevin McHale. 

He won championship titles with the Celtics in 1957 and 1959-1964.

Ramsey is survived by his wife, daughter, two sons, six grandchildren, and two great grandchildren. Rest easy, Mr. Ramsey.
