"My brother was one of my best friends, especially after my mom died, we became so close," Corri Zimmer wrote on Instagram Tuesday morning. "He was always there for me and always the first to show up and volunteer at my foundation events I never even had to ask. Always telling me what a good job I did and how proud he was of me."
Zimmer, 38, had been with the Bengals since late July. He was previously the co-defensive coordinator with the Minnesota Vikings. His NFL coaching career began in 2006 as an assistant linebackers coach with the Saints, with whom he won Super Bowl XLIV.
