Coach Mike Budenholzer hopes to return to the Atlanta Hawks "as soon as possible" after taking a leave of absence to be with his ailing wife.
Budenholzer missed the Hawks' NBA outing in Boston on Friday as Atlanta suffered a 106-93 loss to the Celtics at TD Garden.
The 46-year-old confirmed in a statement on Saturday he had attended a family emergency.
"On Friday morning, I returned to Atlanta from Boston to be with my family due to an emergency medical situation involving my wife. We are encouraged by her progress to this point and remain cautiously optimistic," Budenholzer wrote.
"I would like to take this opportunity to thank the doctors and support staff at Emory for the outstanding care they have provided my wife.
"I would also like to thank my coaching staff, our players and the entire Hawks organisation for their support and encouragement during this time.
"We are humbled by the outpouring of support from so many friends and members of the NBA family. It is greatly appreciated.
"Finally, I'd like to thank the media and our fans for respecting our family's continued request for privacy during this period.
"I will return to the team as soon as possible and will be happy to answer any basketball-related questions at that time."
