Catching up on Thursday's newsbits in the NFC North:
Detroit Lions: The team confirmed via its Web site that cornerback Chris Houston and safety Louis Delmas both have sprained MCLs. That makes both players unlikely to be available for Sunday's game against the Minnesota Vikings. It's a good bet that defensive tackle Nick Fairley (foot) will also be out. Running back Kevin Smith didn't practice Thursday but hasn't been ruled out of Sunday's game. Linebacker Justin Durant (hamstring) sat out practice after working as a limited participant Thursday.
Green Bay Packers: Cornerback Charles Woodson was cleared of concussion symptoms Thursday and should play Sunday against the Oakland Raiders. Running back James Starks (ankle) has missed the past two days of practice and will need to participate Friday if he is going to play. Linebackers A.J. Hawk (calf) and Desmond Bishop (calf) also missed practice again. Meanwhile, quarterback Aaron Rodgers will call into ESPN's Audibles show Thursday night at 7 p.m. ET. Finally, the Packers announced they have sold more than 185,000 shares of stock at $250 apiece since Tuesday. The total offering is 250,000 shares.
Minnesota Vikings: Quarterback Christian Ponder (hip) missed a second consecutive day of practice, and offensive coordinator Bill Musgrave sounded pessimistic about his condition while speaking to local reporters. Ponder will need to practice Friday in order to play against the Lions. Joe Webb has taken the first-team repetitions in practice this week. Tailback Adrian Peterson (ankle) participated in practice Thursday on a limited basis. He has a chance to play Sunday. For those already focused on next season, USC offensive tackle Matt Kalil said he has not decided whether to declare for the 2012 draft. He has one year of eligibility remaining.
