Jones, a Miami Heat guard, won the 3-point title last year in Los Angeles by scoring 20 points in the final round to defeat Boston's Paul Pierce and Ray Allen in the final round. Pierce won the contest in 2010.
The dunk contest will feature Indiana's Paul George, Minnesota's Derrick Williams, Houston's Chase Budinger and Iman Shumpert of the New York Knicks. Last year's champion -- Blake Griffin of the Los Angeles Clippers -- said he wouldn't participate this year.
