Luol Deng will join Bulls in Miami on Sunday, an off day for the team. But his Game 1 availability is questionable.

Deng remains sick, but doctors are not sure exactly what is ailing him. Considering the nature of the illness, there is clearly no timetable for his return, though it's safe to say he'll remain out of the lineup until the second-round series returns to Chicago on Friday. Luol Deng's absence will allow Marco Belinelli to play the wing for the Bulls, as long as he's out of the game.ANALYST: Mobile App
