Former Louisville standout and longtime NBA center Felton Spencer died Sunday, the university announced.

He was 55.

Spencer played at Louisville from 1986-1990. He helped lead the Cardinals to three consecutive Metro Conference tournament wins and a pair of Sweet 16 appearances. He averaged a career-best 14.9 points and 8.5 rebounds during his senior season, and shot 62.8% from the field throughout his collegiate career, which is still the Louisville program record.

Spencer was then selected with the No. 6 overall pick in 1990 by the Minnesota Timberwolves, where he spent his first three seasons in the league. He was named to the all-rookie team after his first season, where he averaged 7.1 points and 7.9 rebounds per game. Spencer also spent time with the Utah Jazz, Orlando Magic, Golden State Warriors, San Antonio Spurs and New York Knicks before he retired in 2002.
