Hall, 20, signed with the Thunder after going unselected in the 2020 NBA Draft. He appeared in 21 games with the team, averaging 4.1 points, 2.8 rebounds and 1.3 assists in 16 minutes per contest.
Oklahoma City tendered Hall a qualifying offer to make him a restricted free agent last month. He ultimately signed the offer, returning to the team on a two-way deal that contained a $50K guarantee.
League rules allow teams to carry 20 players entering training camps, meaning the Thunder now have one two-way spot and two camp spots available to use. The team held the second-worst record in the Western Conference last year at 22-50.
