These are some of the whispers we've heard from around the NFC North lately:
• Expect Vikings CB Chris Cook, the team's top draft pick, to be thrown into the mix right away after coming back from a knee injury. He'll have the bye week to convince the team he should be starting at right corner. When camp broke, Cook was the team's starter there, but the knee injury put the team in a tough position with Asher Allen and Lito Sheppard, with both players being targeted early by opponents.
• The Lions can't afford to suffer too many more serious injuries. For all the improvements the team has made to its talent, it's clear that the roster remains thin on the back end. Injuries to a handful of starters and the benching of OLB Julian Peterson in the second half of the Eagles game in Week Two left the team scratching for solutions.
• Because he's never around, our Packers sources say they don't really have any idea whether or not veteran CB Al Harris' surgically repaired knee is progressing sufficiently enough to enable him to start right away after he serves his six-week stint on the physically-unable to-perform list.
• Bears WR Devin Aromashodu says he's not angry about being in the game for only one play in Week Two. Some have suggested that he was used sparingly because of an injury, but Aromashodu said he had an issue with his knee that he could have played through.
