Boston Celtics (2017–2021)

Following the close of his redshirt junior season, Ojeleye entered his name for the 2017 NBA draft but did not hire an agent, leaving open the possibility of a return to the Mustangs.^[5] Ojeleye was invited to the 2017 NBA Draft Combine, one of 67 participants. After some promising performances he announced that he would commit to the draft, ending his college career. Ojeleye was chosen by the Boston Celtics in the second round with the 37th overall pick.^[6]

Ojeleye made his professional debut on October 17, 2017, in a 102–99 loss to the Cleveland Cavaliers.^[7] During the regular season, he averaged 2.7 points per game and shot 34.6 percent from the field, but emerged as a defensive presence. He started in Game 5 of the playoff series versus the Milwaukee Bucks and held Giannis Antetokounmpo to 16 points.^[8]

Milwaukee Bucks (2021–2022)
