Cavaliers coach Tyronn Lue missed Thursday night's game against Chicago with an undisclosed illness. Lue did his usual media session about 90 minutes before tip-off and was seen in the team's locker room before the game. However, the team announced about 10 minutes before the scheduled 7 p.m. start that Lue would not be coaching the team. Assistant coach Larry Drew filled in for Lue, who is in his third full season as Cleveland's coach. Smith complained of soreness in his knee following the team's morning shootaround and was kept out.
