Isaiah Thomas Speaks About Sister's Death: 'Hardest Week Of My Life'

NBA superstar Isaiah Thomas says "the pain I am feeling right now is impossible to put into words" following his sister's fatal car crash.

Thomas' 22-year-old sister, Chyna, died Saturday in Tacoma, WA after her car violently slammed into a metal pole. Thomas -- who played in Game 1 and 2 of the Celtics' playoff series against the Bulls -- traveled home as the family prepares for the funeral and he's clearly grief-stricken.

He said, "I never could have imagined a day where my little sister, Chyna, wouldn't be here. She and my family are everything to me ... This has been without question the hardest week of my life."

Thomas went on to say he's overwhelmed by the love and support he's received from friends, fans, the City of Boston, the Celtics org and NBA community throughout.
