Young posted a photo to his Twitter of the jersey he was wearing at Saturday's game:
Young played college basketball for the Sooners before declaring for the 2018 NBA Draft. In 2017, he tied a then-NCAA record for single-game assists with 22.
The 22-year-old became the only player to ever lead the NCAA in both points and assists in a single season. He averaged 27.4 points, 3.9 rebounds and 8.7 assists per game while shooting 42.2% from the field and 36% from deep during the 2017-18 college season.
Young was drafted by the Dallas Mavericks in 2018 before being traded to the Hawks, along with a first-round pick for the draft rights to Luka Doncic.
The Sooners are 3-0 this season with wins over Tulane and Western Carolina.
