Retired Celtics star Isaiah Thomas mourns death of elder sister with emotional tribute

Former Boston Celtics star Isaiah Thomas has been through a lot, both on and off the court. Once considered one of the best scorers in the game, the tweener guard recently suffered a grave personal tragedy.

Just seven years after losing his younger sister, Chyna Thomas, the former Sacramento Kings guard lost his elder sister, LaQuish Baldtrip. He announced his sister's death through an Instagram story on Nov. 20.

“Ima miss you big sis!!!!! Damn how you leave me too? 2 sisters gone!!! This can’t be real. I love and miss you queen,” Thomas wrote on Instagram.

Isaiah Thomas grieves the loss of another sister

Thomas isn't a part of the league anymore. Even though not much has been disclosed about his elder sister's death, the mind goes back to 2017 when his other sister died.

Chyna Thomas suffered a car accident on 1-5 at 22 years old. Thomas was just about to play for the Celtics in the playoffs, and he was worn down by the tragedy:

“My teammates didn’t know how to interact or act around me," Thomas said in January on the "View From The Rafters" podcast. "The energy of what we built the last two years kind of got thrown out the window just because I was going through a real-life situation. Physically, I was there. Mentally, I was back at home."

Thomas overcame the odds by becoming an NBA All-Star despite his height – or lack thereof. Back in 2017, he led the league in fourth-quarter scoring, and his offensive outbursts helped the Celtics be one of the teams to beat in the Eastern Conference.

A back injury and a trade shortly after his sister's death took a big toll on his game, and he was never able to get back to his former level.

Thomas has attempted many comebacks ever since. While he's gotten a couple of 10-day deals, he's not likely to get another opportunity to stay on a roster for a full season or play heavy minutes for an NBA team in the future.

Needless to say, basketball might be the last thing going on in his mind right now.
