Early Saturday morning, Isaiah Thomas' 22-year-old sister Chyna died in a one-car collision in their home state of Washington. Her car reportedly veered off of Interstate 5 into a jersey barrier and pole.
The Boston Celtics point guard held is head high as he made the difficult, yet courageous, decision to play in Game 1 of the NBA playoffs on Easter Sunday.
The NBA player didn't learn about his sister's horrific crash until Saturday afternoon, after the team's practice.
Overwhelmed with emotion, Isaiah tried his best to cope with loss of his little sister while preparing for the big game.
