The 66-year-old Dr. Kapoor actor, who is stepping away from the NBC medical drama as his actress-wife Kirron Kher battles cancer, wrote on Instagram Tuesday: "This past year has been difficult for so many people around the world, not least for Dr. Kapoor. It was an incredibly special time for me to part of this show and one I will never forget. The New Amsterdam family will always hold a special place in my heart. I am grateful to the audience for their love, support and good wishes, particularly for my wife, Kirron, at this time. I hope you all will continue to join me on my journey and future projects."
