Jones, a sophomore from Irving MacArthur, has begun treatments after going through a number medical tests and evaluations the past week.
“We hope everyone will keep him in your thoughts and prayers,” a family statement said. “This is obviously a difficult situation for our family, and we hope everyone will respect our privacy at this time.”
Jones was the Longhorns second leading scorer with 13.5 points per game. He missed four games in December after fracturing his right wrist.
“Speaking for our entire team and staff, we love Andrew and will do everything we can to support his family and help him get back to health,” Texas coach Shaka Smart said in a statement. “I want to thank everyone for being respectful of the privacy that the Jones family needs at this time.”
Leukemia is a cancer of the body’s blood-forming tissues, including the bone marrow and the lymphatic system, according to the Mayo Clinic.
“We know Andrew’s a fighter with a strong family and our thoughts, prayers and support are fully behind them,” Texas athletic director Chris Del Conte said in the release. “At The University of Texas, we will do everything in our power to provide all of the resources we can to assist Andrew and his family.”
