CinemaBlend Copy to clipboard NBC's One Chicago universe is no stranger to big shocks and big changes, speaking both in terms of the on-screen narratives and the behind-the-scenes decisions. The youngest drama of the three, Chicago Med just got hit with what is arguably the largest casting shake-up in all of its six seasons, with original cast members Yaya DaCosta and Torrey DeVitto exiting the medical drama ahead of Season 7, and both are heading for different non- Chicago projects. Neither Yaya DaCosta nor Torrey DeVitto appear to be leaving under negative terms, thankfully, and the reason for the two-pronged exit has more to do with all of the original cast members' initial contracts set to expire after Season 6, according to Deadline. That means unless something pretty fatal happens to DaCosta's April Sexton or DeVitto's Natalie Manning, there's always a chance viewers will see them on the NBC drama again in the future, though probably not with the same job duties. Both actresses are clearly hoping for audiences to see them soon in different capacities, also.
