That news shouldn't come as a shock to Rick Pitino, who said last week that he expected the 6-foot-10 Jennings to stay in the draft.
Jennings shared starting duties with freshman center Gorgui Dieng last season, averaging 9.6 points and 5.2 rebounds. Jennings led the Cardinals with 65 blocked shots.
Though he's not projected to be picked in either round of the NBA Draft by most draft experts, Jennings plans to hire an agent, officially ending his chance to return to Louisville next season.
Last weekend, Jennings worked out for NBA scouts in Houston with several other draft hopefuls, including Corey Joseph from Texas. Jennings is expected to workout again for NBA scouts in New Jersey this weekend.
Jennings is the fourth Louisville player under Pitino to forego their remaining eligibility to remain in the NBA Draft, joining Francisco Garcia, Earl Clark and Samardo Samuels. Garcia and Clark were first round selections, while Samuels went undrafted last year before signing as a free agent with Cleveland.
