Ray Knight, a fixture on MASN’s pre- and postgame Washington Nationals coverage since 2007, will not return next season. The network did not pick up his 2019 contract option, according to people familiar with the situation.

MASN pulled Knight off its broadcasts in mid-September, and did not provide any official explanation for the move. But a person with direct knowledge of that decision said the network pulled Knight after he was involved in a verbal altercation with a member of the MASN production team — an exchange in which Knight berated a MASN employee with an expletive-laden tirade.

Knight, 65, did not have a spotless history before the incident. In October 2017, he was arrested for assault-and-battery in connection with an incident at the home he was renting in Alexandria — an altercation that left Knight with a bite on his hand so severe it required stitches. The charges were dropped after he reached a deal with the other party, an unnamed male acquaintance.

He is often a fiery, unfiltered on-air presence, well-known for his candor and occasional inability to mask his feelings about Nationals' shortcomings. The former major league manager and World Series MVP, Knight played 13 seasons in the big leagues, and split that time between Reds, Astros, Mets, Orioles and Tigers.

MASN has yet to decide who will join Nats Xtra host Johnny Holliday in Knight’s place.
