Moussa Cissé Bio
Moussa Cissé (born 10 September 2002) is a Guinean basketball player who currently serves as a center for the Dallas Mavericks of the National Basketball Association (NBA), operating under a two-way contract with the Texas Legends of the NBA G League. Standing at 6 feet 11 inches (2.11 meters) and weighing 220 pounds (100 kilograms), Cissé has established himself as an elite rim protector and shot-blocker throughout his basketball journey. A native of Conakry, Guinea, he moved to the United States at age 14 and quickly developed into one of the most highly decorated defensive players in recent college basketball history. He was a consensus five-star recruit coming out of high school and played for four different college programs before beginning his professional career in 2025.
Early Life and Background
Moussa Cissé was born in Conakry, Guinea, where he spent his childhood immersed in soccer before relocating to New York at the age of 14. This transition marked a pivotal moment in his athletic development, as he shifted his focus from soccer to basketball upon arriving in the United States. His early adjustment to a new country and culture would shape his resilience and adaptability both on and off the court. Growing up in Guinea provided him with a strong foundation in physical literacy and spatial awareness that would later translate to his success as a post player.
Cissé began his high school basketball career at St. Benedict’s Preparatory School in Newark, New Jersey, where he played alongside future NBA player Precious Achiuwa. This early connection would later influence his college decision. He then spent two years at Christ the King Regional High School in Queens, New York, suiting up with another future professional in Kofi Cockburn. During his sophomore year at Christ the King, Cissé led his team to the Class AA state title game, demonstrating his ability to perform on big stages at a young age. His trajectory continued upward when he transferred to Lausanne Collegiate School in Memphis, Tennessee, for his junior and senior seasons.
Path to Basketball
At Lausanne Collegiate School, Cissé elevated his game to elite levels, showcasing remarkable defensive prowess that earned national attention. On 25 November 2019, he recorded an extraordinary stat line of 31 points, 22 rebounds, and 21 blocks in a single game, shattering the Shelby County single-game blocks record that had stood since 1976-77. This performance announced his arrival as one of the most dominant high school centers in the country. He subsequently led Lausanne to the Division II-A state championship, earning tournament MVP honors after contributing 15 points, 10 rebounds, and nine blocks in the championship game against First Assembly Christian School.
As a junior at Lausanne, Cissé averaged 18.4 points, 15.3 rebounds, and 9.2 blocks per game, numbers that underscored his defensive dominance. His 9.2 blocks per game average broke Michael Wilson’s single-season city record for blocks per game, which had been set in 1989-90. These outstanding performances earned him Division II-A Tennessee Mr. Basketball honors, solidifying his status as the top high school player in the state. On 27 May 2020, Cissé made the decision to graduate from high school a year early and reclassify from the 2021 recruiting class to the 2020 class. Despite this accelerated timeline, he maintained his status as a consensus five-star recruit and a top-10 player nationally, drawing interest from virtually every major college program in the country.

Oklahoma State Cowboys (2021–2023)
On 15 July 2021, Cissé committed to Oklahoma State University, choosing the Cowboys over offers from Florida State, Georgia, and Kentucky.
