CLEVELAND — Jim Donovan will no longer be calling Browns games on the Browns Radio Network after announcing that his cancer has returned Thursday.

In a statement issued via the Browns’ social media, he said the cancer is something he’s been dealing with for years.

“I’ve gone through every treatment imaginable,” he said in the statement. “But my cancer is a defiant opponent and has returned and very aggressively. This will require me to devote everything I have in me to continue the fight and my family and I are committed to doing that.”

He said he’s been proud to be “The Voice of the Browns” for the past 25 years and expressed thanks to the fans for their love, support and prayers.

“It’s like having a huge family around us,” he said in the statement. “And that’s what makes the Cleveland Browns so special. You do.”

In a social media post, the Browns thanked Donovan for his work over the past two and a half decades.

“For the past 25 years, Jim Donovan has been synonymous with Browns football and the city of Cleveland,” the team wrote. “His undeniable imprint made on fans across the world with his passionate narration on game days has built a remarkable legacy.”

Browns owners Dee and Jimmy Haslam also issued a statement, saying they were honored to have Donovan as the "Voice of the Browns." 

"He is Cleveland and represents all that is good about Cleveland," they said in the statement. "Jim has poured everything into his craft. Whether you've heard him on TV, radio or have been lucky enough to engage him in person, he lights up every room and every conversation with his infectious energy. His class, professionalism and limitless care for those around him make all of us better. Words could never fully express our gratitude and admiration for Jim, how he has navigated his fight with cancer, his love for this city, and most importantly his love and dedication to his family."

They say he is in their prayers and that they will support him however possible.
