Bolland, Bourque leave with injuries
Bolland originally went to the dressing room briefly midway through the first period after blocking a shot by Nashville defenseman Shea Weber.
Following a faceoff in the Chicago zone, Weber's drive from the point struck Bolland in the abdomen, but he returned minutes later for two more shifts in the first.
Bolland then left again following two shifts in the second period.
The Predators said Bourque suffered an upper-body injury.
