Erica Telfair, the mother of former NBA and Abraham Lincoln High School star Sebastian Telfair, died early Monday after battling the virus, although her official cause of death is unknown. She was 64.

Her passing comes after her son and Sebastian’s older brother, Dan Turner, died March 28 from COVID-19. Former Lincoln head coach Dwayne “Tiny” Morton confirmed both deaths.

During an interview with the Undefeated in late March, former Knicks and Nets guard Stephon Marbury, Telfair’s cousin, said Turner died from COVID-19.

He also noted that Telfair’s mom was “fighting for her life” at the time because of “this virus.”

Both Sebastian and younger brother Ethan Telfair, who played at Lincoln and Idaho State, posted remembrances of their mother on social media Monday. “Let me see them X-rays. I ain’t no expert. We just hurt!” was posted on Sebastian’s Instagram story along with his mom’s name, her birthday and the day she died.
