Alan Williams has stepped down as defensive coordinator of the Chicago Bears.

"I am taking a step back to take care of my health and family. I appreciate the opportunity to work with the Chicago Bears, a storied NFL franchise with a rich history," Williams said in a statement.

"I value the NFL shield and all that it stands for and after taking some time to address my health, I plan to come back and coach again," he added.

Williams, 53, has been away from the Bears since last week with what the team classified as a personal reason.
