The Oklahoma City have agreed to fully guarantee the final two seasons of Lu Dort's contract for the 21-22 and 22-23 season.
Dort is averaging 12.4 points and 3.6 rebounds per game.
Dort went undrafted in 2019 out of Arizona State and was subsequently signed to a Two-Way contract by the Thunder.
The Thunder converted Dort to a standard NBA contract in June on a four-year, $5.4 million deal.
