Vikki Zimmer, the wife of Cincinnati Bengals defensive coordinator Mike Zimmer, died Thursday in Cincinnati.
Details of her death were not available. The Zimmers were married for 27 years and had three children.
"We are stunned and saddened to learn of Vikki's passing," Bengals president Mike Brown said in a statement Friday. "She was a warm and popular person in the Bengals family, and our immense respect and affection for Mike makes this especially hard. Our hearts are out to Mike and his family."
It is uncertain whether Mike Zimmer will coach this weekend when the Bengals play the Ravens in Baltimore.
Zimmer is in his second season as Bengals defensive coordinator. He served in the same capacity for the Atlanta Falcons in 2007, and with the Dallas Cowboys for the seven seasons prior to that. Zimmer was on Dallas' staff between 1994 and 2006.
"Mike is part of our Bengals family, and we'll support him in every way we can," Bengals coach Marvin Lewis said. "We will dearly miss Vikki. She was a friend to all of us, and a big supporter of Mike's players. Her thoughtfulness to them in so many ways will also be greatly missed."
