Honestly, it still feels weird watching the 21st District without him. You know the feeling. Antonio Dawson was basically the moral compass of Chicago PD, the guy who actually tried to follow the rules while Voight was busy dragging people to the "Silos."
For six seasons, Jon Seda played Antonio as the perfect foil to Hank Voight’s chaotic energy. He wasn't just a detective; he was the guy who reminded us that being a cop used to mean something specific. Then, suddenly, he was just... gone. No big hero moment. No dramatic shootout. Just a mention of rehab and a one-way ticket to Puerto Rico.
If you’re still scratching your head over how such a major character got such a quiet, almost messy exit, you’re not alone.
What Actually Happened to Antonio from Chicago PD?
The downfall started with a shoulder injury. It sounds like a small plot point, right? Wrong. In Season 6, Antonio got hooked on oxycontin. He wasn't partying; he was just trying to stay on the job. But as anyone who watches this show knows, nothing stays simple in Chicago.
Things hit a breaking point in the episode "Descent." Antonio's daughter, Eva, gets kidnapped by a dealer because of a bust gone wrong. By the time they find her, Antonio is high and completely unhinged. He ends up pushing the kidnapper out of a window to his death.
Voight and Ruzek covered it up. That was the beginning of the end. Antonio, the guy who lived for the "proper way" of doing things, couldn't live with himself. He relapsed hard in the Season 6 finale, and by the time Season 7 premiered, the show basically told us through a conversation that he’d resigned and moved to Puerto Rico to be near his sister, Gabby.
The Real Reason Jon Seda Left the Show
Fans were pretty vocal about how "out of character" the addiction storyline felt. It’s a valid gripe. Antonio had been a rock for years—originally appearing on Chicago Fire before moving to PD, and even headlining the short-lived Chicago Justice.
So, why did the writers do him like that?
According to reports from Deadline at the time, the producers felt the character had "played out." Essentially, they ran out of stories to tell for him. It wasn't a scandal or a contract dispute. It was just a creative decision to rotate the cast.
"It was an honor portraying Det. Antonio Dawson," Seda posted on X (formerly Twitter) after the news broke. He was a pro about it, but even he seemed surprised by the sudden pivot.
It’s kind of a bummer because Antonio represented a version of policing that Chicago PD eventually moved away from. He was the "good" guy in a unit full of anti-heroes. When he left, the show lost that internal friction that made the early seasons so tense.

Why the Puerto Rico Ending Still Stings
Look, we get why they chose Puerto Rico. It connects back to his family roots and his sister’s exit from Chicago Fire. But it felt rushed. One minute he’s a drug-addicted cop who just committed a "justifiable" murder, and the next, he’s just... living his best life off-screen?
It felt like the writers painted him into a corner and then realized they didn't have a ladder to get him out.
Is There a Chance for an Antonio Dawson Return?
If you're holding out hope for a cameo, don't hold your breath, but don't give up either. Jon Seda has always said he’s open to it. "The door is always open," showrunner Rick Eid once mentioned in an interview with CinemaBlend.
The character is still alive. He’s healthy (presumably). He has deep ties to the unit. With the show entering its later seasons, a legacy return would be a massive win for the fans who stayed through the post-Halstead era.
What You Should Do Next
If you’re missing that classic Chicago PD vibe, here’s the play:
- Rewatch Season 4, Episode 8: This was his original "exit" when he moved to Chicago Justice. It shows Antonio at his peak—competent, respected, and moving up.
- Check out Jon Seda in La Brea: If you just miss the actor, he spent three seasons on this NBC sci-fi show. It’s a totally different vibe, but his screen presence is still top-tier.
- Keep an eye on the One Chicago crossovers: Even if he doesn't return to PD, the writers love mentioning him on Fire or Med whenever Gabby Dawson is brought up.
Antonio from Chicago PD might be gone for now, but in the "One Chicago" universe, nobody is ever truly forgotten.
