Layups: The Bulls planned to monitor Zach LaVine after Thursday’s practice, but his minutes restriction is expected to increase from 24 to “26 or 28,” according to Hoiberg. … There’s no change in Kris Dunn’s status and no timetable for his return from the concussion he suffered Jan. 17. “You can still tell he’s tired,” said Hoiberg, who visited with Dunn at the Advocate Center. “He’s sleeping a lot, which is a good thing to get his rest. It’s very important that he stays hydrated throughout this process.” … Lonzo Ball, whose father, LaVar, has created plenty of headlines, has been sidelined since Jan. 13 with a sprained left knee. But Holiday, whose brother Aaron played with Ball at UCLA, complimented the Lakers rookie for his poise. “I really admire the way he's been mature about everything media-wise,” Holiday said. “He's always been good, done his own thing, been calm and (he) continues to play regardless of the outcomes of the games.
