Taking to Twitter, Seda wrote, "Though saddened with @chicagojustice I'm humbled by all the love from the #OneChicago fans, thank you! Also, many thanks to DickWolf & @NBC."
Seda's Chicago Justice mention is a reference to the series being canceled after one season.
The actor initially left P.D. to join Justice, and now makes his triumphant return.
A couple of months ago, Chicago P.D. alum Sophia Bush chose to exit the series, leaving fans devastated.
Ultimately, it was reported that she chose to leave on her own terms and not because she was forced out by a change in creative direction.
Seda coming back into the fold is making fans from all over giddy with excitement.
One follower wrote, "I'm happy to hear you are feeling all the love and outpouring of support for your return to Chicago PD. WE LOVE YOU!"
Another said, "So happy you are coming back to #ChicagoPD #ChicagoJustice was a great show should of gotten another season so happy you will be back on PD!"
While most fans are expressing sadness that Justice didn't get another season, they all seem to be very happy that Seda is staying with the franchise.
