Fox was born in Atlanta and attended Gordon High School in Barnesville, Georgia.

Then, on February 1, 1968, he was part of a big trade which sent him and Happy Hairston to the Detroit Pistons for Tom Van Arsdale and John Tresvant.

Just after the completion of the 1969–70 season, on April 23, 1970, Fox was again traded, this time along with a second-round draft pick to the Chicago Bulls for Clem Haskins.

The Kansas City-Omaha Kings (formerly the Cincinnati Royals) traded him along with Dick Gibbs to the Seattle SuperSonics for a second-round pick.
