Saturday was the second season finale for Transplant on NBC with 1.34 million viewers.  The show originally was running Sunday evening but was moved to Saturday after poor ratings.  Oddly Transplant had better ratings on Saturday which is the graveyard for US network programming.  Transplant had much stronger ratings on NBC for season one and often won it's timeslot which was on Tuesday evenings.  The show has never had under one million viewers on CTV.

Transplant is renewed for Season three by CTV but no word on NBC.  Speculation is that the show would continue in the US on Peacock, Hulu, Netflix or CW if not picked up by NBC.  More from TV Series Finale..https://tvseriesfinale.com/tv-show/transplant-season-three-has-the-nbc-tv-series-been-cancelled-or-renewed-yet/
