A capsule look at reasons for concern among teams in the NFC South: Atlanta Falcons 1. Pass coverage. CB Dunta Robinson, the team's major offseason acquisition, has not played in three exhibition games because of a hamstring injury. He will likely get some action tonight at Jacksonville. If he's not 100 percent, the Falcons' chance of improving the 28th-ranked pass defense diminishes greatly. Robinson is supposed to play on the right side and take away that side of the field.

A capsule look at reasons for concern among teams in the AFC East: Buffalo Bills 1. Left tackle. The Bills might not be good enough at the position. LT Demetrius Bell struggled mightily last season and has gotten limited preseason reps coming off knee surgery, so stamina might be an issue. RT Cornell Green has not looked good in pass protection. The Bills must limit long-yardage situations because shaky pass protection could endanger QB Trent Edwards.

First, no Ben Roethlisberger. Now, maybe no Byron Leftwich for the Pittsburgh Steelers. Dennis Dixon, you're up next. Leftwich, expected to be the fill-in starter for the suspended Roethlisberger at quarterback for the Steelers, sprained his left knee in the second quarter as Pittsburgh (3-1) beat the starter-less Carolina Panthers 19-3 in the preseason finale Thursday night.

A capsule look at reasons for concern among teams in the NFC West: Arizona Cardinals 1. Quarterback. Obviously, the QB situation is a huge concern. The club is open to trading Matt Leinart, and new starter Derek Anderson hardly is a proven commodity. If Leinart leaves, either Max Hall or John Skelton, both rookies, would be the backup. With the QB situation unsettled, it might take awhile for the offense to find a rhythm. 2. Inside linebacker. This position remains a real concern with two new starters in place.

A capsule look at reasons for concern among teams in the AFC West: Denver Broncos 1. Inexperience/injuries on O-line. Denver likely will start two rookies — LG Zane Beadles and C J.D. Walton — and while there's talent, there's a learning curve. To compound matters, LT Ryan Clady has only recently returned to practice coming off knee surgery and RG Chris Kuper has some ankle issues. Continuity will take some time. 2. Pass rushers. There have been signs OLB Robert Ayers might be ready to make a step forward.

A capsule look at reasons for concern among teams in the NFC East: Dallas Cowboys 1. Lack of touchdowns. The first-string offense has scored only one offensive TD in 12 possessions — an 8-yard drive set up by a turnover — and has shown little production rushing or passing. Obviously, they don't do much game-planning or sophisticated play-calling in preseason, but they didn't do it last year, either, but were a lot more productive in preseason.

OAKLAND, Calif. – The end of the exhibition season brought encouraging signs for the Oakland Raiders and Seattle Seahawks when it comes to their backup quarterbacks.

The end of the exhibition season brought encouraging signs for the Oakland Raiders and Seattle Seahawks when it comes to their backup quarterbacks. Bruce Gradkowski threw two touchdown passes in the first quarter and the Raiders mostly used backups to end the preseason with a 27-24 victory over the Seahawks on Thursday night.

Leinart trade rumors blow ahead of Cardinals' final cuts While rumors swirled about his future with the Arizona Cardinals, Matt Leinart was competent in limited action Thursday — which has been the case all preseason, SN correspondent Kent Somers reports. And that, Somers says, might be enough for him to remain with the team. Before kickoff against the Washington Redskins, stories began to circulate that the Cardinals had given Leinart's agent permission to pursue a trade.

SAN FRANCISCO – On a night when San Francisco's offensive stars sat out, the 49ers got more big plays on the other side of the ball to cap their first unbeaten pre-season in 18 years.
