San Antonio has signed guard Miles Barnstable to an Exhibit 10 contract. He is expected to head to the Austin Spurs in the G League once preseason wraps. Barnstable went undrafted out of Tulsa in 2026 after averaging 14.6 points and 3.8 rebounds on efficient shooting as a senior.

Detroit signed undrafted wing Jordan Riley out of East Carolina to a camp deal. Chicago added guards Houston Mallette and Peter Suder, the latter waived by the Lakers off a two-way deal in July.
