With very little having gone right for the Philadelphia Eagles and Dallas Cowboys of late, both teams understand what's at stake Sunday in this crucial NFC East clash.

Philadelphia tries to avoid dropping five straight for the first time under coach Andy Reid when it hosts Dallas, which has lost four of five.

Since winning three of their first four games, the Eagles' season has taken a turn for the worse. Philadelphia (3-5) saw its woes continue Monday in a 28-13 road loss to New Orleans, which sacked Michael Vick seven times thanks to a dismal display from the Eagles' depleted offensive line.

"I've just got to believe in the guys in front of me and do whatever it takes to get the ball out whether I've got to slide or move, break contain," said Vick, who will continue to start under center. "Regardless, I just have to continue to maintain trust in them. That's part of my job as a quarterback and I have to keep believing. Keep believing."

Already without left tackle Jason Peters, center Jason Kelce and right guard Danny Watkins, Philadelphia suffered another big blow when Todd Herremans suffered a dislocated bone and ligament damage in his right foot. The right tackle was placed on season-ending injured reserve Wednesday.

Herremans' absence could make things all the more difficult on Philadelphia, which can't afford to slip any further in the standings. The Eagles are in a second-place tie with Dallas, 2 1/2 games behind division-leading New York.

Philadelphia hasn't been handed five straight losses since opening 0-5 in 1998 - the season before Reid took over.

"We've got to find a way to win a football game," said Vick, who completed just 22 of 41 passes for 272 yards with a touchdown and an interception against the Saints. "We miss that feeling of winning and it's been a long time since we've had one, so it's important to come out this week, have a great week of practice, a great week of preparation and get ready to play a good football game."

The Cowboys (3-5) are in a similar situation, knowing another loss Sunday could prove too much to overcome.

"We've dug ourselves a hole and we just got to keep fighting," defensive end Jason Hatcher said. "We've got the right guys to do it, we just have to go out there and believe and do it, stop talking about it and be the team that we're supposed to be."

Dallas is coming off Sunday night's 19-13 loss at undefeated Atlanta, giving up a season-high 453 yards of total offense. The Cowboys settled for field goals on their first two drives and scored their only touchdown with 5:21 remaining in the game.

"There have been too many different things," said tight end Jason Witten, who hauled in seven catches to become the team's all-time leader with 754, surpassing Michael Irvin. "(Teams) that are good in this league are consistent. That's not what we've been.

"Each week it's different, and you've got to eliminate it and get it fixed. ... The results have got to come. They've got to come soon."

While Tony Romo threw for 321 yards with a TD, the Cowboys managed just 65 yards on the ground. Dallas is averaging 83.4 rushing yards to rank 29th in the league and could have a hard time running the ball again with DeMarco Murray (sprained foot) likely to miss a fourth consecutive game.

The Cowboys, though, are hoping to have linebacker Dan Connor available after he sat out last week with a neck injury.

"A desperate football team? I wouldn't say that at all," coach Jason Garrett said. "You've heard me use the word urgent a lot around here. We believe in urgency 365 days out of the year. That's where we are right now. We have to be urgent in our preparation ... getting ready for the Philadelphia Eagles on Sunday."

The Cowboys are looking to avoid a third consecutive loss in this series after dropping both matchups last season by a combined 54-14. Vick threw for 572 yards, four touchdowns and no interceptions in those games, improving to 3-0 as a starter against Dallas since 2010.Source from http://www.cbssports.com/nfl/gametracker/preview/NFL_20121111_DAL@PHI/cowboyseagles-preview

 
 
The Jaguars have won the last three games between these two AFC South rivals, including this season as well as the 2011 season finale. But Colts quarterback Andrew Luck isn't just some rookie in his third NFL start like he was the last time the Jaguars saw him.

No, Luck is now a full-blown prodigy who has the Colts in the playoff discussion with four wins in the last five games since that loss to the Jaguars. Luck is also coming off a game in which he threw for a rookie-record 433 yards last Sunday in a win over the Miami Dolphins.

Luck's four 300-yard passing games this season have tied Peyton Manning's rookie franchise record, set in 1998.

The difference will be:Can the Jaguars muster any sort of offense? Jacksonville continues to reside at the bottom of the league rankings in every major offensive category.

They are last in yards per game (254.4), last in points per game (14.6), last in passing yards per game (170.4) and 29th in rushing yards per game (84.0). And in what may be the worst bit of bad news in all of it is the Jacksonville defense is also last in the league in sacks with eight.

If they can't rattle Luck or match him touchdown for touchdown, that sets up to be a tough night.
