Pregnancy Prompts NBC to Shift Chicago Med to Fall and Heartbreaker to Midseason

With star expecting, medical shows change places

NBC is swapping one new medical drama for another this fall.

The network announced that Chicago Med, its Chicago Hope/Chicago P.D. spinoff that had been slated for midseason, will instead debut this fall on Tuesdays at 9 p.m. The show, produced by Dick Wolf, takes the place of another medical drama, Heartbreaker, which the network said "is being revised due to [star] Melissa George's pregnancy."  

Both shows will begin production this summer. NBC released its initial 2015-16 lineup on May 10.

Pregnancy aside, the swap makes a lot of sense for NBC, which is coming off its second consecutive season win among adults 18-49 and hopes to carry that momentum into the fall. Chicago Med was one of the network's most anticipated new shows, given the solid ratings for Chicago Fire and Chicago P.D., while Heartbreaker is one of Adweek's least promising broadcast pilots based on reaction to trailers shown during upfronts. 

NBC's change in schedule comes three days after ABC made its own fall season moves: shifting drama Quantico to Sundays at 10 p.m. in place of drama Of Kings and Prophets, which is being recast. ABC's plans for Tuesdays at 10 p.m., where Quantico was initially scheduled, remain up in the air. 

With more than three months left before the fall season kicks off, there's still plenty of time for CBS, Fox and the CW to counter with their own schedule tweaks.
