Another member of Firehouse 51 is departing.

On Tuesday's episode of Chicago Fire, Jimmy Borrelli (Steven R. McQueen) was badly burned during a response call after disobeying an order from Chief Boden (Eamonn Walker), thus putting an end to his career as a firefighter. McQueen, who joined the show in Season 4, will no longer be a series regular, has confirmed.

On the show, Borrelli and Boden have been feuding since the end of last season, when Borrelli blamed Boden for his brother's death at a scene.

Executive producer Michael Brandt had previously indicated that the rivalry between Borrelli and Boden would result in one of them leaving the house — but he tells TVLine that the decision to have the axe fall on Borrelli was almost a foregone conclusion.

"Eamonn [Walker] has been with us since Day 1," Brandt said. "He was the first character we cast. He's Papa Bear in Chicago. I think [executive producers] Derek [Haas], Matt [Olmstead], myself or Dick [Wolf] would all be fired before Eamonn would be. ... He's on the show as long as he wants to be."

Brandt says there are currently no plans for McQueen to make future guest appearances on the show.

"The discussions with Steven were nothing but pleasant. He was a total professional about it," Brandt told TVLine. "He understood, and I think he's embracing the opportunity to go and be the No. 1 on his own show."
