Jimmy Butler (shoulder) is listed as questionable to face the Cavs on Thursday.
He is only dealing with a muscular shoulder injury and it would appear he at least has a shot to play. Mike Dunleavy (ankle) is probable, so the Bulls might not need him quite so badly. If Butler does sit, Tony Snell will look to build off his 24-point game on Tuesday. He's still not a great fantasy play in most leagues, though. Butler owners will want to check back for more information at shootaround Thursday morning.
My own personal thinking is they sit him and let him go enjoy his first All-Star Game, but that is just speculation on my part.
