Jones was the Longhorns leading scorer before he was sidelined by a broken wrist.
"After undergoing a number of tests and evaluations over the past week, Andrew has been diagnosed with leukemia", Jones' family said in a statement.
Minutes after stunning No. 16 TCU, 99-98, in double overtime, teary-eyed Texas players held up Andrew Jones' No. 1 jersey during postgame celebrations Wednesday. "This is obviously a hard situation for our family, and we hope everyone will respect our privacy at this time".
Concern regarding Jones' health first arose in late December when he returned from a fractured wrist but did not look himself.
When the game does tip off at 8 p.m. on ESPNU, Texas will have to face a a tough TCU team.
Shaka Smart and the Longhorns let their emotions show after a hard day in Austin.
Now we have a better idea of what Jones is up against, though Texas did not offer many specifics. "I hope he knows we love him". On the final possession of the game, TCU point guard Jaylen Fisher drove unimpeded to the basket for what appeared to be an uncontested game-winning layup, but his attempt wound up falling harmlessly off the front rim.
Jones was averaging 13.5 points, 2.4 rebounds and 2.0 assists per game this season for the 10-5 Longhorns. He was the catalyst for a strong start to the season for Texas that included wins over Butler and VCU and overtime losses to national powers Duke and Gonzaga.
As the Texas pep band played The Eyes of Texas, the Longhorns' fight song, Jones' teammates stood at attention. All they want now is for Jones to get healthy again.
