"My family and I have decided that it is best for me to test the waters," Jones said in a statement released by the Longhorns. "We want to see where I stand in the draft, but we're also looking to improve my game as well. We are looking to get accurate feedback from NBA personnel to know my scouting report, so that I can get better during this offseason."
The 6-foot-4, 190-pound Jones averaged 11.4 points and 3.9 rebounds this past season, and he tied for the team lead in assists at 3.5 per game.
Texas finished 11-22 and was 4-14 in the Big 12.
Freshman Jarrett Allen declared for the draft, as well, and he also did not hire an agent to maintain his college eligibility.
ESPN's Chad Ford has Jones going No. 26 to the Brooklyn Nets in his most recent mock draft.
