"All parties have concluded that at the current time it is best for Aldridge to refrain from play until further tests and examinations are completed," the Spurs said in a press release.
At the end of his rookie season with the Portland Trail Blazers in April 2007, Aldridge was diagnosed with Wolff-Parkinson-White syndrome, which is an abnormality that can cause a rapid heartbeat.
Aldridge, 31, underwent a procedure to fix the problem and missed the final nine games of the season. Four years later, he underwent the same procedure and missed time at the start of the 2011-12 season when there was a recurrence of his condition.
The 6-foot-11, 260-pound Aldridge, a five-time All-Star, is in his second season with the Spurs after nine campaigns with the Trail Blazers.
Aldridge is averaging 17.3 points, 7.4 rebounds and 1.1 blocked shots in 58 games this season.
Forward Kawhi Leonard already was out because of a concussion.
The Warriors recalled rookie center Damian Jones from the Santa Cruz Warriors of the NBA Development League and he will be in uniform for the Spurs game.
Guard Kyle Korver was scheduled to miss his second straight game because of a sore right foot when the Cleveland Cavaliers played at the Orlando Magic on Saturday.
Korver also sat out on Thursday's game at Detroit, when the reigning NBA champions lost their third consecutive contest.
Coach Tyronn Lue said Korver is expected to undergo further tests and "they're going to re-evaluate in a few days."
The Los Angeles Lakers signed guard David Nwaba to a second 10-day contract.
The 6-foot-5, 204-pound Nwaba is averaging 2.6 points, 1.6 rebounds and 11.2 minutes in five games with the Lakers after being recalled from the team's NBA Development League affiliate on Feb. 28.
