NFC North at night

Chicago Bears: Veteran linebacker Cato June was cut after spending two weeks on the roster as insurance for an ailing Lance Briggs. With Briggs healthy, the Bears made room on their roster to promote offensive lineman James Marten from the practice squad.

Detroit Lions: While saying he remains committed to holding players accountable for Sunday’s 48-3 loss at Baltimore, coach Jim Schwartz announced no roster moves or lineup changes Monday. He said there will be no “sacrificial lambs” for the sake of sending a message. Here is the link to a transcript of Schwartz’s lengthy news conference, where he also said that quarterback Matthew Stafford’s left shoulder is “unchanged.” That means Stafford will have to make more progress before he returns to the field.

Green Bay Packers: Defensive lineman Johnny Jolly (knee) will miss some practice time this week, coach Mike McCarthy said Monday. The Packers hope to test nose tackle Ryan Pickett’s hamstring later this week.

Minnesota Vikings: Coach Brad Childress acknowledged that “none of us have a great feel for” receiver Percy Harvin’s most recent bout with migraine headaches. As of Monday, there was no indication when Harvin will return to practice. Childress, meanwhile, said he was happy with the performance of rookie safety Jamarca Sanford during Sunday’s game against Cincinnati. But Tyrell Johnson (concussion) will regain his starting job whenever doctors clear him to return.
