NBC's medical drama 'Chicago Med' is set to return for its 10th season on September 25, with Sarah Ramos and Darren Barnet joining the cast as series regulars. Ramos will portray Dr. Caitlin Lenox, while Barnet takes on the role of Dr. John Frost. Their addition follows the exit of Dominic Rains, who played Dr. Crockett Marcel since Season 5, with uncertainty surrounding his possible return. The upcoming season promises to address lingering cliffhangers from Season 9, particularly involving Dr. Mitch Ripley, and will explore the dynamics of a dysfunctional family within the emergency department. The series maintains its core cast, including S. Epatha Merkerson and Oliver Platt, and is produced by Universal Television in collaboration with Wolf Entertainment.
