The Wolves are adding free agent forward Kyle Anderson, who played the past four seasons for Memphis, an NBA source confirmed.
The deal is for two years and $18 million.
Free agency officially opens at 11 p.m.
The 6-9 Anderson is an eight-year veteran. He played his first four seasons for the San Antonio Spurs after they drafted him in the first round (30th overall) in 2014 out of UCLA.
Anderson, 28, averaged 7.6 points and 5.3 rebounds per game last season as the Grizzlies claimed the No. 2 seed in the Western Conference and beat the Wolves in the first round of the NBA playoffs.
