The Blazers also announced center Meyers Leonard is out 2-3 weeks with a left ankle sprain.
Aldridge has been having an MVP-caliber season as the leader of the Blazers, who have been one of the NBA's biggest surprises. He's averaging 23.9 points, 11.4 rebounds, 2.8 assists and 1.00 blocked shot in 53 games this season.
Pretty amazing too that with Aldridge out, this will be the first game all season a Portland starter has missed.
Leonard, their backup to the backup center, is averaging 2.7 points, 3.0 rebounds and 0.3 minutes in 21 games this season.
