NFC North in the evening

Some final tidbits as the countdown continues to Packers-Lions II:

Detroit Lions: What a mess the Lions have at safety. They placed starter Ko Simpson (knee) on injured reserve and declared Kalvin Pearson (hamstring) out of the game. Fellow starter Louis Delmas (ankle) is questionable but likely to play. Still, that leaves Marvin White as the only other safety available on the active roster. White was claimed off waivers from Dallas last month. … Linebacker Ernie Sims (hamstring) has also been declared out for the game, while quarterback Matthew Stafford (shoulder) and defensive end Dwayne White (toe) are doubtful and unlikely to play. … Receiver Calvin Johnson (knee, hand) is questionable but will be limited at best if he plays.

Green Bay Packers: An MRI showed no damage on center Scott Wells’ knee, so it appears he will start Thursday. Wells told Wisconsin reporters that “nothing’s torn” and that the swelling has receded. He’s officially listed as probable. Tailback Ahman Green (groin) and tackle Allen Barbre (ankle) are the only two players the Packers likely won’t have available to them.
