Chicago Bears defensive coordinator Alan Williams has resigned, saying he needs to tend to his health and his family. Williams’ resignation comes just two games into his second season. In a statement, Williams thanked the Bears and their front office and ownership, and vowed to coach again. He missed last week’s loss at Tampa Bay for what the team said were personal reasons after working the opener against Green Bay. Coach Matt Eberflus called the defense in Williams’ absence and figures to do so again when the Bears visit Patrick Mahomes and the Kansas City Chiefs on Sunday.
