Elhadji Tacko Sereigne Diop Fall (born 10 December 1995) is a Senegalese professional basketball player for the Xinjiang Flying Tigers of the Chinese Basketball Association (CBA).
Fall was born and raised in Dakar, Senegal. In 2011, Senegalese basketball coach Ibrahima N'Diaye, the brother of former NBA player Mamadou N'Diaye, heard from a friend about an exceptionally tall teenager he had seen playing with friends in a local street. After identifying him, they visited the 15-year-old Fall—who already stood 7 ft 3 in (2.21 m) tall—at his home and persuaded Fall's mother, Marianne Diop Sene, to allow Fall to start attending N'Diaye's basketball academy. Fall moved to the United States at age 16. He first played organized basketball in Houston, Texas, and trained with NBA Hall of Famer Hakeem Olajuwon.
Due to his height and reach, Fall was one of the most highly scouted high school basketball centers in the nation. Fall first played for Jamie's House Charter School in Houston, where his team won the state championship. Fall played with ISTI all-stars summer travel team & for Each 1 Teach 1 on the Nike Elite Youth Basketball League (EYBL) circuit where he played alongside fellow class of 2015 recruits Antonio Blakeney and Ben Simmons. He also played in several NCAA certified events, including the NBPA Top 100 Camp in Virginia. Fall then attended Liberty Christian Preparatory School in Tavares, Florida. As a senior in 2015, Fall averaged 20 points, 15 rebounds, and 5.1 blocks per game. Rated as a four-star and three-star recruit in the 2015 high school class and nearly forty different schools expressing interest in him, Fall committed to the University of Central Florida in Orlando, who officially signed him on October 28, 2014. He played with the UCF Knights under head coach Donnie Jones.
Fall played college basketball at University of Central Florida for Knights as a center. He faced fellow giant Senegalese center Mamadou N'Diaye (unrelated to the former NBA player of the same name), who stands at 7 ft 6 in (2.29 m), in the tallest tip-off and match-up in US college basketball history in a game against University of California Irvine. Both men come from the same city, Dakar. By his sophomore year, after N'Diaye declared for the 2016 NBA draft, Fall became the tallest player in college basketball. During his sophomore season, Fall would make considerable improvements in his playing style. In 2017, Fall was named American Athletic Conference Defensive Player of the Year.
Fall grew to be an efficient player, ranking second nationally in field goal percentage as of January 2017. On 5 April 2017, Fall declared for the 2017 NBA draft, with the possibility of returning to Central Florida still available to him before the end of the draft lottery that year. On 24 May 2017, Fall withdrew his name from consideration for the NBA draft, to return to UCF for his junior year. During his junior year, Fall injured his shoulder, causing him to only play in 16 games, totaling 351 minutes. Coming into his senior season, Fall was named to the Preseason Second Team All-AAC. During his senior season, Fall helped lead the Knights to the 2019 NCAA tournament and secured their first victory in program history with a win over Virginia Commonwealth University. In his final game, Fall recorded 15 points and six rebounds in a losing effort against Duke University 77–76.
Despite going undrafted in the 2019 NBA draft, Fall was signed to an Exhibit 10 Contract on June 21, 2019, by the Boston Celtics. Fall played for the Celtics during the 2019 NBA Summer League season, scoring six points in his first game alongside four rebounds; in his second game he tallied twelve points for his first double-digit scoring game, alongside another rebound. He had one blocked shot in each of his first two games. Fall concluded his 2019 Summer League run participating in all five games with the Celtics and averaging 7.2 points, 4.0 rebounds, 1.4 blocks, and shooting a team-high 77 percent from the field.
On July 25, 2019, the Celtics officially announced that they had signed Fall. On October 13, 2019, the Celtics officially announced that they had signed Fall to a two-way contract, splitting time between the Celtics and Maine Red Claws.
