Catching up on some NFC North newsbits as a busy day winds down:
Chicago Bears: Linebacker/special-teams ace Brian Iwuh was waived after suffering a minor hamstring injury last Sunday. An injury settlement will follow. Iwuh had a team-high 14 special-teams tackles this season. The Bears promoted linebacker Patrick Trahan from their practice squad to take his place.
Detroit Lions: Four starters didn't participate in a bonus Tuesday practice: Cornerback Chris Houston (knee), safety Louis Delmas (leg), running back Kevin Smith and defensive tackle Ndamukong Suh (suspension). Defensive back Brandon McDonald (leg) also didn't practice. Delmas isn't expected to play Sunday night at the New Orleans Saints and likely will be replaced by Chris Harris. The Lions gave themselves some depth behind Delmas and Harris by promoting practice-squad safety Ricardo Silva. Punter Ryan Donahue was placed on injured reserve to create that roster spot.
Green Bay Packers: Linebacker Erik Walden, arrested last Friday after a domestic incident with his girlfriend, apologized to his teammates and in an interview session with reporters. Walden has not been formally charged.
Minnesota Vikings: The Minnesota state Senate held the first of two public hearings on the Vikings' stadium issue. This hearing centered around site options. The team wants the project built in suburban Arden Hills, Minn. But Vikings officials were encouraged during the hearing to work with Minneapolis officials to select one downtown option for comparison's sake, if nothing else. Meanwhile, the Vikings signed long-snapper Matt Katula to replace Cullen Loeffler, who suffered a fracture in his lower back Sunday against the Atlanta Falcons.
