Professional career
After graduating from the university, Gipson was interested in the NBA and European professional teams but drew the attention of NFL teams. He trained with the Green Bay Packers in the spring of 2015 despite never playing competitive football before. “The main things I want to work on are my footwork and getting low and moving and blocking,” Gipson said. He gave up on the idea after figuring that climbing up to the NFL level would have taken at least two years of work. In September 2015, Gipson became a professional basketball player in Europe after signing a one-year contract with the Finnish team Kouvot. Gipson averaged 13.2 points, 8.1 rebounds and 1.2 assists per game on the season. The Kouvot progressed to the finals where it faced Tampereen Pyrintö. In the fourth game, Gipson was ejected for kicking his feet at Joonas Cavén. The Kouvot won the Finnish Championship in 4-1 series. After the end of the Finnish season in May, Gipson moved to the Mexican team Halcones de Ciudad Obregón. In September 2016 he moved to the French team, Élan Chalon and averaged 2.9 points and 3.4 rebounds in eight games. He was released by Élan Chalon in November and signed with the Ukrainian team BC Khimik. After a brief stay in Ukraine, in January 2017 Gipson joined Correcaminos Colon of the Panamanian league and averaged 8 points and 5.8 rebounds per game. He signed with the French team Boulazac Basket Dordogne on February 18. Gipson rejoined Kouvot in September, signing a one-year contract.
