10:55 AM PST -- Thomas tells TMZ, "I love Criminal Minds and have put my heart and soul into it for the last twelve years. I had hoped to see it through to the end, but that won't be possible now. I would just like to say thank you to the writers, producers, actors, our amazing crew, and, most importantly, the best fans that a show could ever hope to have."
Thomas Gibson won't get his kicks from "Criminal Minds" anymore ... because he was just fired.
Producers put the word out Friday ... he won't return to the show for the 12th season.
TMZ broke the story, the actor was suspended from the show after kicking a writer/co-executive producer in a dispute over a scene that Gibson was directing. And, as we reported, a few years ago he was ordered to anger management classes after striking someone else on the crew.
ABC, which produces the show, and CBS, which airs it, issued a blunt statement: "Thomas Gibson has been dismissed from Criminal Minds. Creative details for how the character's exit will be addressed in the show will be announced at a later date."
