Shortly before the start of the playoffs, Celtics guard Isaiah Thomas found out some tragic personal news. Here’s the Boston Herald reporting:

Isiah Thomas plays through personal tragedy

Just one day after losing his sister in a tragic car crash, NBA star Isaiah Thomas chose to play with the Boston Celtics in their first playoff game. Although he was clearly devastated, sobbing on the bench before the game, Thomas had a longtime friend and teammate supporting him.

Fellow Celtics player Avery Bradley was spotted putting his arm around the 28-year-old point guard as he cried during the pregame shoot around. The two athletes grew up together in Tacoma, Washington, before becoming NBA teammates.

After learning that his 22-year-old sister, Chyna J. Thomas, died in a one-car crash in Tacoma early on Saturday morning, the basketball player opted to play on Sunday. He ended up scoring 33 points, although the team lost to the Chicago Bulls.

“It says a lot about him,” Bradley said after the game, according to NBA.com.
