Chicago Med is adding to its ranks.
The Hollywood Reporter says Arrow Star Colin Donnell has joined the Chicago Fire spinoff as a new series regular.
It is still unclear who Donnell is playing since he did not appear in the backdoor pilot for the new series, which aired as an April episode of Chicago Fire. Donnell joins previously cast series regulars Oliver Platt, S. Epatha Merkerson, Laurie Holden, Nick Gehlfuss and Yaya Dacosta.
The series is said to cover the city’s most explosive hospital and the courageous team of doctors who hold it together.
