NFC North at night

Posted by ESPN.com’s Kevin Seifert

Catching up on a newsy day in the NFC North:

Green Bay has lost safety Atari Bigby for at least a month after he sustained what coach Mike McCarthy called a “significant” knee injury Sunday night against Chicago. McCarthy said Aaron Rouse will start Sunday against Cincinnati. I wonder if the Packers have any second thoughts about waiving safety Anthony Smith, who was claimed earlier this month by St. Louis.

I think we can officially label Bigby “injury-prone.” He missed three games in 2006 because of a hamstring injury and was limited to seven games last season by injuries to his ankle, hamstring and shoulder. He signed his one-year tender as a restricted free agent this offseason, a deal worth $1.545 million, and you wonder what his future will hold with the Packers.

Detroit announced it has 4,000 tickets remaining for Sunday’s home opener against Minnesota. Officially, the Lions have until 1 p.m. Thursday to sell them or face a local television blackout. Teams typically apply for at least one 24-hour extension if they are within striking distance.

The Lions also claimed former Kansas City defensive tackle Turk McBride on waivers and released defensive lineman Orien Harris. ESPN's Adam Schefter reports that Chicago also placed a claim on McBride. The Lions had priority because their record was inferior last season.
