The Minnesota Timberwolves are attempting to acquire free-agent forward Nicolas Batum in a three-team trade with the Portland Trail Blazers and Chicago Bulls, a league source told ESPN The Magazine's Ric Bucher.

Portland would receive shooting guard Kyle Korver from Chicago and two future first-round draft picks from Minnesota, according to the source. The Bulls would acquire a second-round pick from the Timberwolves, the source said.

The Timberwolves will sign Batum to an offer sheet if the deal can't be completed by Wednesday night, the source said.

But Minnesota is trying to avoid the risk of Portland matching the offer sheet by compensating the Blazers the future picks and Korver as a replacement for Batum.

Blazers general manager Neil Olshey said Wednesday the team would match any offers for Batum, who reportedly agreed with the Timberwolves on a four-year, $45 million offer with bonuses that could push the deal past $50 million.

Agent Bouna Ndiaye also told The Associated Press that Batum wanted to play for the Wolves and that they hoped the Blazers either would not match the offer or execute a sign-and-trade.

A four-year veteran, the 6-foot-8 Batum averaged 13.9 points and 4.6 rebounds -- both career highs -- with Portland this past season.
