For many Sunday-morning TV viewers, Charles Osgood has become a habit so ingrained that missing his “CBS Sunday Morning” would be like forgoing eggs and coffee. At some point in the not-too-distant future, however, the ritual of watching the veteran may come to a close.

CBS News and Osgood have begun discussing when he might leave the show, according to a person familiar with the situation. There is no set date when the newsman might step down, this person cautioned, though he is scheduled to be absent from the program for a few weeks due to knee surgery. Osgood’s negotiations were previously reported by the New York Daily News.

CBS declined to make executives available for comment.

Among the pool of potential successors would be Jane Pauley, the former “Today” anchor who joined CBS News as a contributor in 2014.
