When Michael Weatherly left the show, he said that Tony DiNozzo would "live on in the hearts and minds of the viewers” and that, in terms of a return, he "would absolutely be open to anything and everything, including things that no one's even thought of yet," according to Newsweek. Furthermore, in 2018, he tweeted, "I will always be ready to play DiNozzo when the time is right" (via Twitter).

And now, he is leaving "Bull," as well. "It's been my privilege to play Dr. Jason Bull but after 6 Seasons of incredible storylines, I've decided it's time to pursue new creative challenges and bring his story to a close," he said on Twitter yesterday. "It has been an honor to work with this talented cast, crew, and writing/producing team who helped reinvent the legal drama. Stay tuned for a big series finish ... Thanks to all the fans from the bottom of my heart. You will always be a part of our Bull family!"

There are 12 episodes left in this current and final season, Season 6.
