Ousmane Cisse studied at Montgomery Catholic High School in Montgomery, Alabama, U.S., where he and his teammates won the 2A State Championship. In his first appearance as a Catholic Knight, he broke the Alabama High School Athletic Association's record for block shots in the first half against Horseshoe Bend. He later attended St. Jude Catholic High School in Montgomery, and after graduating he signed up to the 2001 NBA Draft and was selected as a 46th pick overall by the Denver Nuggets.
After he was signed by the Denver Nuggets in 2001 he was injured and released. He then moved to the Harlem Globetrotters. After a year he returned to play in the NBA signing with the Orlando Magic. Ousmane was released just after one game and moved to play in the USBL. In 2003, he signed with the Toronto Raptors and was released after a couple of days, without ever playing with the team.
Cisse started his international career when he signed at Bnei HaSharon in Israel for the 2005–06 season. He led the league in Rebounds (10.1 per game) and blocks (2.5), but the team finished only in the 9th place. Ousmane then stayed three more seasons in Bnei HaSharon reaching the State Cup final in the 2006–07 season and finishing at the 3rd place in the Israeli League in 2007–08.
