Towns missed Minnesota's final game before the All-Star break after an MRI revealed a wrist injury. He will be re-evaluated in two weeks.
Towns is averaging a career-best 26.5 points and 10.8 rebounds per game this season.
The injury means the Wolves will have to wait to see how the team looks with Towns playing alongside newly acquired point guard D'Angelo Russell.
Towns, who had been an iron man in his first three seasons, missed 15 games earlier this season with a sprained left knee.
