Alexandra "Sasha" McHale, the 22-year-old daughter of Houston Rockets coach Kevin McHale, died on Saturday, the Houston Chronicle reported. McHale has been on a leave of absence from the team to be with his daughter and his family in Minneapolis since Nov. 10. She had battled lupus, an auto-immune disease. "I extend my deepest condolences to Kevin and Lynn for the loss of their beautiful daughter, Sasha, on Saturday afternoon," Rockets owner Leslie Alexander said in a statement on Sunday. "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." Rockets assistant Kelvin Sampson has been the team's acting head coach in McHale's absence. It's not clear when McHale will return to the team.
