The Timberwolves sent Wiggins, a 2021 protected first-round draft pick and a 2021 second-round pick to the Warriors in exchange for Russell, swingman Jacob Evans and forward Omari Spellman, according to the team.
League sources told ESPN the 2021 draft choice is top-three protected. If it falls in the top three, it transfers to 2022 and is unprotected.
The Timberwolves were searching for a point guard to pair with star big man Karl-Anthony Towns. Russell was taken with the No. 2 overall pick in the 2015 NBA Draft, one selection behind Towns.
Wiggins is averaging 22.4 points and 5.2 rebounds per game this season. He is in the second year of a five-year, $140 million contract.
