Tim Duncan (bruised chest) is questionable for Saturday's game vs. the Blazers, and beat writer Jeff McDonald describes Duncan's timetable as "fluid." "Whatever it is, I don't know," Popovich said, when asked about Duncan's return. "When they tell me he's ready to play, then he'll play." That typically opaque quote from Popovich leaves owners with no choice but to bench Duncan until he's officially cleared to return. The Spurs don't return to action until Tuesday at Denver, and it wouldn't be surprising if they rested Duncan on Saturday to give him three extra days of rehab.
