Yaya Dacosta’s new series is headed to television sooner than expected…

NBC is tweaking its fall schedule, replacing the new medical drama Heartbreaker with the 32-year-old part-Brazilian American actress’ new series Chicago Med.

The network had announced a fall 2015 Tuesday lineup consisting of The Voice leading to Heartbreaker and new variety show Best Time Ever with Neil Patrick Harris, to be succeeded by NBC Tuesday 10 PM anchor Chicago Fire in November, when Best Time Ever’s run ends.

Chicago Med, which originated as a planted spinoff episode of Chicago Fire this past season, was previously slated for a midseason launch but will now debut in September behind The Voice. Starting in November, it will form a Chicago 9-11 PM block, paired with the franchise’s mothership series.

The scheduling change stems from the pregnancy of Heartbreaker star Melissa George, who is expecting her second child.

Both Heartbreaker and Chicago Med will start production in mid-summer, but Heartbreaker will then go on hiatus to accommodate George’s pregnancy.

Dick Wolf’s Chicago Med is described as an emotional thrill ride through the day-to-day chaos of the city’s most explosive hospital.

Chicago Med also stars Oliver Platt, S. Epatha Merkerson, Laurie Holden and Nick Gehlfuss.
