The Chicago Bulls may have something else to add to their laundry list of woes this season.

Joe Cowley of the Chicago Sun-Times reported on Thursday that Bulls center Nikola Vucevic had an incident with new teammate Patrick Beverley during Wednesday’s win over the Detroit Pistons. Beverley apparently called out Vucevic in the fourth quarter over a blown defensive rotation, leading to to words being exchanged between the two. They eventually were separated by Bulls veteran DeMar DeRozan.
