鈥淚t has been an honor to play Dawson on聽Chicago Fire聽and one of the most meaningful experiences of my life,鈥 Raymund聽said in a handwritten note she shared on聽Twitter. 鈥淚 am so thankful for the journey and especially to all of you for watching, but I have made the decision that it鈥檚 time for me to move on to the next chapter in life.鈥

The news comes after聽season 6鈥檚聽May 10 finale. Raymund has played the role of paramedic-turned-firefighter Gabriela Dawson on Chicago Fire聽since its 2012 debut. Her character has also appeared on the show鈥檚 two spinoffs, Chicago P.D.聽and Chicago Med.

鈥淚鈥檒l always be proud to have played a fierce paramedic with such an incredible cast and crew,鈥 she wrote. 鈥淥n to the next! See you on the ice.鈥

Fellow cast members Jesse Spencer (Captain Matthew Casey, who聽plays Dawson鈥檚 husband on the show), Taylor Kinney (Lieutenant Kelly Severide), and Eamonn Walker (Chief聽Wallace Boden) were also up for contract renewal, and have聽reportedly signed on for next season.
