If you joined in on NBC this week for the One Chicago episodes, just to find reruns being aired, there's a reason for that. Chicago Fire, Chicago Med, and Chicago PD were not streaming a new episode this week in their usual Wednesday 8/9c timeslot.
One Chicago was on another hiatus this week, owing to which, there were no scheduled new episodes this Wednesday on NBC. All three shows, Chicago Fire, Chicago Med, and Chicago PD, left off at very interesting plot points, so this hiatus was extremely frustrating.
Here's why no One Chicago episodes were airing this week.
No One Chicago episodes this week: Details Explored
One Chicago is on a weekly hiatus before it returns for a final phase of streaming from May 7, 2025. The shows took a similar two-week hiatus just recently in March, but luckily, it is a very short one this time around. It was announced in the NBC 2-week schedule that there wouldn't be any new episodes for Chicago Fire, Chicago Med, and Chicago PD until May 7. Sometimes there's no clear reason for such breaks, and such is the case with the shows.

The broadcast season ends in mid-May, so it is not surprising that the show has taken a hiatus right before streaming the final episodes for the season. This is a common practice for shows so that they have enough power-packed episodes to last them until the end of the broadcast season. One Chicago is possibly on a similar break and will return with three high-voltage episodes for all three shows.
NBC was streaming reruns of Episode 6 from the respective seasons instead of new episodes in the scheduled time slot on the last Wednesday of April. Chicago Fire, Chicago Med, and Chicago PD are only a few episodes away from their season finale for this season. All three shows have three more episodes left to stream before they take a final break before another season. The shows will be returning from this short break on Wednesday, May 7, 2025, and will then three air for the next three weeks without a break until their season finale on May 21, 2025.
After the season finale premieres, we will not see Chicago Fire, Chicago PD, and Chicago Med until the next broadcast season, so it will definitely be a heartfelt goodbye this time around. Additionally, Chicago Fire is set to say goodbye to two of its major characters, Sam Carver and Darren Ritter, so the season finale will be even more heartbreaking for fans of the show.
While we wait for new episodes of One Chicago to air on May 7, all the previously aired episodes from Season 12 of Chicago PD, Season 13 of Chicago Fire, and Season 10 of Chicago Med, along with all the previous seasons, are available to stream on Peacock.
Chicago PD Season 12 Episode 20, Chicago Fire Season 13 Episode 20, and Chicago Med Season 10 Episode 20 will air on NBC on May 7, 2025, and will be available to stream on Peacock.
