Cincinnati Bengals offensive analyst and former Minnesota Vikings co-defensive coordinator Adam Zimmer has died, his sister Corri announced in a heartbreaking Instagram post Tuesday. He was 38 years old.

Corri shared a picture of her brother and wrote, "Adam, you were the light of our lives." She went on to say that he was the best husband, father, brother, partner, coach, mentor and friend anyone could ask for. She and her family are asking for privacy as they mourn his loss.

New tragic details have emerged in the death of the 38-year-old assistant coach. A new court filing obtained by the Star Tribune of Minneapolis suggests that alcohol was a factor in Zimmer's demise. Police were called to his home for a welfare check last week and were told that he had been drinking excessively. When they arrived, they found him on his couch. There was a woman at his residence, but authorities did not identify her.

Zimmer's NFL coaching career began in 2006 with the New Orleans Saints as an assistant linebackers coach. He spent the next seven seasons with the Kansas City Chiefs and then returned to Minnesota with his father Mike Zimmer in 2014. Zimmer became their linebackers coach in 2014, and was promoted to co-defensive coordinator in 2020. The Vikings fired the team's coaching staff after a disappointing 2021 season, and Zimmer joined the Bengals' staff in July.

Tributes have poured in for the longtime NFL assistant coach, who was working remotely from his Twin Cities home this season. The elder Zimmer served on his son's Vikings coaching staff for nine seasons before the pair parted ways after the 2021 campaign.
