Boston Celtics forward Josh Richardson has agreed to a one-year, $12 million extension, his agent Bill Duffy of BDA Sports told ESPN's Adrian Wojnarowski.
Richardson had one year and $11.5 million left on his deal, which now runs through the 2022-2023 season.
The Celtics acquired Richardson from the Dallas Mavericks last month by using the remainder of the trade exception created by the sign-and-trade deal that sent Gordon Hayward to the Charlotte Hornets in November.
Richardson averaged 12.1 points in 59 games with the Mavericks last season.
