Kirk Herbstreit has shared a heartbreaking farewell note. Ben, the beloved dog of the college football commentator, has passed away.

Ben had battled Leukemia. He continued to accompany Herbstreit to college and pro football games in recent weeks, but had experienced a recent decline in health after a second chemo injection in late October.

Herbstreit shared Thursday via social media that he had to say goodbye to Ben.

“This is really hard to write but so many of you have loved and cared about Ben that I wanted to let you know,” Herbstreit wrote. “We found out today the cancer had spread throughout Bens organs and there was nothing left we could do-we had to let him go. I’ve had dogs my whole life but Ben was 1-of-1.

“He was smart-loving-gentle-patient-inquisitive-and welcoming to all. Always a big smile and a soft tail wag. He and I could communicate..he and I understood each other and had each others backs. He was with me more than anyone at home and traveling with me for work. Such an easy going companion. Hard day-but he will live within all of us forever. God please bless his majestic soul and thank you for putting him in my life for the last 10 years-a true blessing.

“Love you Ben. “

Herbstreit will be in Baton Rouge this weekend for College GameDay and on the call of the top-15 rivalry showdown between LSU and Alabama.

RIP to a favorite Good Boy of college football fans everywhere.
