An abbreviated look at what’s going on around the NFL on Tuesday, Sept. 6:
• The Cowboys continue to hold out hope that their starting cornerbacks, Terence Newman and Mike Jenkins, will be healthy enough for Week 1 action. So far, neither player has been able to even practice.
• With the Ravens signing ex-Cowboys center Andre Gurode, questions naturally arose about starting center Matt Birk's health -- he missed a substantial amount of time this preseason. But Birk says he's not worried.
• The Patriots released James Sanders and Brandon Meriweather, meaning that Josh Barnett and Sergio Brown will have every opportunity to win a starting safety spot. • How will the Eagles' linebackers fare in 2011? At least one scout is convinced that "it's a very, very average group."
