Silvio De Sousa (born 7 October 1998) is an Angolan professional basketball player who last played for Aris of the Greek Basket League and the EuroCup.

[3] After having to share playing time with top prospects and forwards Simisola Shittu and E. J. Montgomery, he chose to leave the program after his sophomore season.

Although IMG also had touted big men, Isaiah Stokes and Emmitt Williams, his decision ultimately gave him more playing time than at Montverde.

[5] In August of his senior year, De Sousa committed to Kansas and reclassified from the recruiting class of 2018 to 2017 while exploring the chance to graduate early from IMG Academy and join the Jayhawks in time for the second semester of the 2017–18 NCAA season.

Gassnola further testified that he gave $2,500 to Falmagne to cover the cost of online courses that De Sousa needed to graduate high school early.

He also agreed to pay $20,000 to Falmagne to help release De Sousa from the commitment to the Maryland booster, but that the proposed payment was never made.

[21] On 5 August 2021, De Sousa was found not guilty of aggravated battery in a case stemming from 1 January 2020, shortly before the brawl against Kansas State.

According to the complaint, De Sousa had been involved in an early morning altercation outside of a bar in Douglas County which resulted in a man losing sight permanently in one of his eyes.
