Derrick White will not be testing NBA free agency in the summer of 2025. The veteran guard is sticking with the Boston Celtics.

White and the Celtics have agreed to a four-year, $125.9 million contract extension, ESPN’s Adrian Wojnarowski reported Monday. The contract includes a player option, per Wojnarowski. The deal will begin during the 2025-26 season because White still has one more year left on his current contract.

Here’s the year-by-year salary breakdown, per ESPN’s Bobby Marks:

The Celtics acquired White in a trade with the San Antonio Spurs before the 2022 NBA trade deadline. The C’s gave up Romeo Langford, Josh Richardson, a 2022 first-round pick and a 2028 first-round pick swap (top-one protected).

From the day he arrived, White has become a fan favorite in Boston with his excellent two-way play and hustle.

White averaged 15.2 points, 4.1 assists, 3.5 rebounds, 0.9 blocks and 0.8 steals per game during the 2023-24 regular season. He also shot 46.1 percent from the field and a career-high 39.6 percent from 3-point range.

White’s defense was stellar all season, and his effort was rewarded with a place on the league’s All-Defensive second team for the second consecutive year.

The 29-year-old guard was fantastic in the playoffs, too, averaging 16.7 points, 4.3 rebounds and 4.1 assists per game, while shooting 40.4 percent from beyond the arc. White scored 15-plus points in 12 of the team’s 19 playoff games en route to winning the NBA Finals over the Dallas Mavericks.
