Warriors coach Don Nelson has been asked to stay away from the team so that his health can be re-evaluated.
He has missed five of the team's last six games due to pneumonia, returning for Golden State's loss to Houston on Thursday night.
Nelson has suffered two dizzy spells since rejoining the team and general manager Larry Riley told Yahoo! Sports he asked Nelson to take Friday's practice off to rest.
"I'll have him slow down [Friday]," Riley said. "I'm concerned for him personally, but he'll be all right. We'll see. It's a slow process."
Nelson has also expressed doubt about whether he'll physically be able to travel with the team on their upcoming four-game road trip, which begins Sunday.
