Detroit
The Lions placed defensive tackle Cory Redding on season-ending injured reserve. Langston Moore re-joined the team as his replacement. Receiver Shaun McDonald (ankle) also won't play Sunday at Indianapolis. Defensive end DeWayne White (calf) is expected to play, according to defensive coordinator Joe Barry. Cornerbacks Leigh Bodden (groin) and Keith Smith (groin) will have their status determined Sunday morning.

Green Bay
Safety Atari Bigby (ankle) is out, leaving Charles Woodson to start his third consecutive game at safety. Fullback Korey Hall (knee) is doubtful and not expected to play Sunday at Jacksonville. Defensive tackle Justin Harrell returned to practice Friday but is questionable because of a sore hip. His status might not be clear until Sunday morning. Linebacker Brandon Chillar (groin) is probable and expected to play.

Minnesota
Quarterback Gus Frerotte (back) and right tackle Artis Hicks (elbow) are doubtful and aren't expected to play Sunday at Arizona. Tarvaris Jackson and Ryan Cook, respectively, will replace them. Rookie kick returner Darius Reynaud (toe) has been ruled out as well. Defensive end Jared Allen (knee) returned to practice Friday and should start.

Linebacker Ernie Sims (knee) won't participate in the Detroit Lions' preseason opener Thursday against the N.Y. Giants.

Sims suffered a bone bruise in his right knee July 27 and returned to practice Monday. Coach Rod Marinelli said Wednesday that most starters will get in for only about 10 plays. Other players scheduled to sit out include: Defensive tackle Cory Redding (groin), guard Edwin Mulitalo (elbow) and defensive tackle Langston Moore (shoulder).

Quarterback Dan Orlovsky will be the first quarterback off the bench, followed by Drew Stanton.
