Starring Taylor Kinney, David Eigenberg, Eamonn Walker, Christian Stolte, Joe Minoso, Kara Killmer, Miranda Rae Mayo, Alberto Rosende, Daniel Kyri and Hanako Greensmith, the Chicago Fire series follows the first responders at Fire Station 51 in the Windy City.
Spencer (pictured) played firefighter Matt Casey since the beginning of the long-running NBC series but left the drama in its tenth season. He briefly returned to the series after the tenth-season finale for the wedding of firefighters Severide and Kidd (Kinney and Mayo).
Spencer will appear on the Wednesday, April 5 episode of Chicago Fire. It is not yet known when Kinney will return to the NBC series.
