Chicago Med: Arrow Alum Colin Donnell Joins Spinoff as Series Regular

Colin Donnell Chicago Med

One of Arrow‘s dearly departed cast members has found new life on Chicago Med.

Colin Donnell, who played Tommy Merlyn on the CW series, has joined NBC’s Chicago Fire spinoff in a series-regular role.

Not much is known about Donnell’s character just yet, since work on the midseason series is only beginning, but Deadline reports he will likely play a doctor, possibly in pediatrics.

Donnell joins a cast that includes Laurie Holden (The Walking Dead), S. Epatha Merkerson (Law & Order), Oliver Platt (Fargo), Yaya DaCosta (Ugly Betty) and Nick Gehlfuss (Shameless).

The actor also appeared on Season 1 of Showtime’s The Affair and recently guest-starred on The Mysteries of Laura and Person of Interest.
