The Boston Celtics have locked up Jaylen Brown for at least the next few years.

Boston announced it reached a contract extension with the 22-year-old, who was set to hit restricted free agency at the end of the season. The Celtics had until 6 p.m. ET on Monday to reach an extension with the wing. While the team did not disclose the details of deal, it is reported the extension is worth $115 million over four years.

According to Chris Haynes and Keith Smith of Yahoo! Sports, Brown has a total guaranteed salary of $103 million, with the other $12 million being tied to incentives for Most Valuable Player, Defensive Player of the Year and All-NBA Teams. He has a starting base salary of $23.88 million per year, with eight percent raises each season.

Brown is entering his fourth season with the Celtics, who made the wing the third overall pick in the 2016 draft. Brown has played in at least 70 games in each of his three seasons, which bodes well for that particular incentive.

In 222 career games, Brown is averaging 11.2 points, 4.0 rebounds, 1.3 assists and 24.4 minutes.
