In a statement issued this morning, Rockets owner Leslie Alexander said, "I extend my deepest condolences to Kevin and Lynn for the loss of their beautiful daughter, Sasha, on Saturday afternoon. Kevin and Lynn are loving and dedicated parents who will need our continued support throughout this very difficult time. Our entire organization is mourning the McHale family's loss and we ask that you keep them in your thoughts and prayers."
Coach McHale took a leave of absence from the Rockets earlier this month with assistant coach Kelvin Sampson stepping in to take over his duties. There is no timetable for Kevin McHale's return.
At the time, Rockets general manager Daryl Morey didn't provide any further details on the specifics of the situation, but expressed his concern for McHale.
"Kevin is a devoted family man who is needed back home in Minnesota at the moment," Morey said. "The Rockets organization will keep Kevin and his family in our thoughts and prayers during this difficult time."
Sasha just turned 23 last month. She reportedly had the auto-immune disease lupus and was recently hospitalized with a related condition.
Additional details were not immediately released.
Some players were showing support for their coach Sunday on social media.
"R.I.P. Sasha," Chandler Parsons tweeted Sunday.
James Harden shared his condolences on Twitter as well. "Praying for Coach McHale and his family," he wrote.
McHale spent several years with the Minnesota Timberwolves as a coach and executive before joining the Rockets following two seasons as a television analyst.
"While Kevin was with our organization, we all watched Sasha grow up and become an outstanding young woman," Timberwolves owner Glen Taylor said in a statement. "She will be sorely missed by her family and friends."
