After working out De’Aaron Fox earlier in the day, the Lakers are hosting another top-five prospect for a private workout this afternooon. The team announced today that former Kansas forward Josh Jackson will be in town for an audition (Twitter link). It will be the second time the Lakers have gotten a first-hand look at Jackson, having met with him in Sacramento last week. Jackson’s workout with the Lakers comes on the heels of a Monday report indicating that he cancelled a workout with the Celtics, who have the No. 1 overall pick in the draft. There has been speculation that Jackson received a draft promise, but Steve Kyler of Basketball Insiders tweets that the Lakers have told agents that haven’t made any promises to anyone.
