Omicron has put NCIS season 19 on hold.

The infectious variant of COVID-19 has interrupted several TV productions, and NCIS is one of them. There's been a positive test among the cast and crew, and it's believed an actor has become infected, according to Deadline.

NCIS season 19 delayed: COVID outbreak on set

The NCIS star with COVID-19 hasn't been identified. What the positive test means for the show also remains a little unclear.

A source told Deadline the shoot could be delayed for "a couple of weeks," but it may also resume at the end of this week.

After a month off, NCIS had finally aired a new episode this past Monday. It's also scheduled to show new episodes on Jan. 17 and Jan. 24, so it's possible the COVID incident won't disrupt plans for season 19 on CBS.

NCIS is one of several series that, according to Deadline, have stopped to "evaluate" their plans amid the spread of Omicron. Chicago Fire has also paused filming, and NCIS: LA has delayed its return to set.

The latest seasons of NCIS were cut short due to setbacks from COVID-19. The show typically produces 24 episodes per season, but it had just 16 last year and 20 the year prior.

An episode count for season 19 hasn't been confirmed yet. In the meantime, we wish a speedy recovery to all who have tested positive.
