SAN ANTONIO (AP) — San Antonio Spurs guard De’Aaron Fox has agreed to a four-year, $228 million maximum contract extension, a person with knowledge of the situation said Monday.

The extension starts in 2026-27, said the person, who spoke with The Associated Press on condition of anonymity because the Spurs have yet to announce the agreement.
