McRoberts will draw the start in Wednesday's matchup with the Spurs, Jason Lieser of The Palm Beach Post reports.
Analysis:
McRoberts is drawing the rare start because Luol Deng was a late scratch from the lineup. McRoberts should see a heavier workload than usual, but still draws a very difficult matchup with the the Spurs' stingy frontcourt defense. It is unclear how much time Deng will miss, but if he misses any more McRobert could continue grabbing some extra minutes.
