Aldridge will undergo further testing before the Spurs determine how much time he misses.
The 6-foot-11, 260-pound Aldridge was diagnosed with Wolff-Parkinson-White syndrome — an abnormality that can cause a rapid heartbeat — at the end of his rookie season in April 2007.
He missed the final nine games of that season with the Trail Blazers after the original diagnosis. He also missed time at the start of 2011-12 when there was a recurrence of his condition.
The Spurs also announced that point guards Tony Parker (back stiffness) and Dejounte Murray (groin tightness) won't play Saturday night against the Golden State Warriors. San Antonio already is without star forward Kawhi Leonard, who is in the concussion protocol.
