Let's catch up on some news threads on a busy Monday in the NFC North:
Chicago Bears linebacker Pisa Tinoisamoa, who has missed two of the past three games because of a knee injury, has had what coach Lovie Smith termed a "minor" procedure on the knee. It's not clear how many more games Tinoisamoa will miss, but it's probably safe to assume he won't play Sunday against the New England Patriots. Nick Roach will remain the starter if he recovers from a hip injury that sidelined him last Sunday against the Detroit Lions. Otherwise, backup middle linebacker Rod Wilson would be next in line.
The Minnesota Vikings agreed to terms with tailback Lorenzo Booker, who has played this season for the Hartford Colonials of the UFL. Interim head coach Leslie Frazier said the Vikings hope to use Booker as a third-down back. The Vikings did not announce a corresponding roster move.
