College career
On May 16, 2016 it was announced that Yurtseven would be playing college basketball at North Carolina State University.[10] However, due to his previous exposure with playing for Fenerbahçe, in some professional games, the NCAA decided to suspend him for the first nine games of their season (around 30% of the schedule), as well as require him to donate $1,000 to a charity of his choosing, in exchange for him to be fully eligible for playing time moving forward.[11] After fulfilling his suspension, he returned to the court on December 15, in a win against Appalachian State University. On March 14, 2017, Yurtseven would test out his stock for the 2017 NBA draft, leaving open the possibility that he would return to North Carolina State for his sophomore season.

On March 21, 2018, Yurtseven would test out going pro once again for the 2018 NBA draft. However, even if he stayed in college, he confirmed that he would not return to North Carolina State and would instead request a transfer to a different university.[12]
