ANALYSIS: Zeller took a hard hit to the face from veteran forward Andre Iguodala in Portland's preseason home opener vs. the Warriors. It's unclear how long the broken nose will keep Zeller off the floor for, but the Blazers will hope the big man recovers in time for the season opener in about two weeks.
