Bulls.com (Sam Smith) reports: The Bulls got some good news Sunday when the x-rays for Luol Deng and Tim Thomas were negative. Both will be listed as day to day and uncertain about playing Tuesday in Charlotte. Deng and coach Vinny Del Negro had speculated after Saturday’s win over Houston that Deng could have a season ending stress fracture. Though that also raises the question of who will play and when. One of the big questions coming into Saturday’s game was the status of the starting lineup after the poor effort and big loss in Washington Friday, then the third loss in four games.
