GREEN BAY, Wisc. — What can Aaron Rodgers do for a rip-roaring Lambeau Field encore this weekend?

Chip Kelly would like to not have to find out Sunday, when his Philadelphia Eagles pay a visit to play the Green Bay Packers at Lambeau Field for a highly anticipated matchup of NFC title contenders.

“That’s the huge challenge,” Kelly, the Eagles’ second-year head coach, said Wednesday about catching Rodgers just a week after his latest passing performance for the record book.

Rodgers needed only the opening two quarters to match Green Bay’s single-game benchmark for touchdown passes (six) – and tie a 45-year-old NFL standard for the first half – in the Packers’ 55-14 drubbing of the Chicago Bears at Lambeau on Sunday night.

“I said it our guys (Tuesday), I think he’s playing as good as any quarterback in the league right now, probably the best quarterback in the league right now,” Kelly said. “He’s on top of his game. It doesn’t seem like you can fool him. He’s always kind of a play ahead, a step ahead of defenses and defensive coordinators.

“He always seems to find the open receiver, no matter how it kind of unveils itself pre-snap. He’s extremely accurate, as good a thrower as there is in this league. He can keep things alive because he’s such a good athlete. It’s an exciting challenge for us to go against the best.”

Considering Kelly has quickly established himself as one of the league’s offensive gurus with the Eagles’ ability to score at will in their fast-break attack, those are some significant comments of high praise.

Not that Rodgers is paying any attention to the pregame hype that the Packers (6-3), who are a game behind NFC North front-runner Detroit, could be engaged in a shootout with the NFC East-leading Eagles (7-2), who have scored points in almost every way possible this season.

“It’s their offense against our defense,” Rodgers contended. “We’re focused on their defense and trying to find ways to move the ball.”

All Rodgers did against the Bears last time out was move the football into the end zone six times in seven possessions, turning the prime-time game into an hour-long comedy for TV viewers as Green Bay built a 42-0 halftime lead.

Rodgers was out of the game by the midway point of the third quarter. On Wednesday, he earned his third NFC Offensive Player of the Week honor in the first 10 weeks this season and leads the league with a staggering passer rating of 120.1.

Yet, as usual, Rodgers isn’t resting on his laurels, especially given what may be at stake Sunday. His absence for seven games the final two months of last season because of a broken collarbone, starting with a 27-13 loss at home against the Eagles, nearly kept Green Bay from winning a third straight division title and returning to the playoffs.

A year later, the Packers not only are trying to overtake the Lions but also likely will need to improve to 5-0 at Lambeau this season to keep Philadelphia from gaining what could be a crucial head-to-head tiebreaker come January.

“They’re in a tight race in the East, and we’re in a tight race in the North,” Rodgers said. “We’ve got to win these kind of games at home if you want to have a postseason potential.”

SERIES HISTORY: 39th regular-season meeting. Packers lead series, 24-14. The Eagles snapped a three-game losing streak to Green Bay when they prevailed 27-13 at Lambeau Field last November, when the Packers played their first of seven straight games without injured quarterback Aaron Rodgers. Philadelphia has won two of the last three meetings in Green Bay and six of the past nine encounters overall going back to 2003. The teams met twice in the postseason in that span – a 20-17 overtime victory for the Eagles at home in the divisional round of the NFC playoffs during the 2003 season and a 21-16 Packers win at Philadelphia in the wild-card round during their Super Bowl-winning 2010 season.

MEDICAL WATCH: OGs Josh Sitton (toe) and T.J. Lang (ankle) did not practice Wednesday and will rest most of the week, but are expected to play against the Eagles. … TE Brandon Bostick didn’t practice Wednesday. Sparingly used on offense this season, the second-year player is dealing with a hip injury that apparently came on during the blowout victory over the Bears on Sunday. … OLB Jayrone Elliott was a non-participant for practice Wednesday. The undrafted rookie, who has been contributing on special teams, has a hamstring injury that flared up coming out of the lopsided win over Chicago.

GAME PLAN: Since their debut season in the National Football League in 1921, the Packers had never scored more than 30 points in each of their first four home games – until this season. Green Bay’s big- and quick-strike offense with a few contributions from opportunistic defensive teammates has thrown up 31, 42, 38 and 55 points in wins over the New York Jets, Minnesota Vikings, Carolina Panthers and Chicago Bears, respectively, thus far at Lambeau Field.

There’s no reason to think the Packers won’t keep their scoreboard operator from blinking Sunday, especially when the Philadelphia Eagles figure to be just as gung-ho to get their frenetic offensive moving up and down the field.

Working in Green Bay’s favor for outpointing the Eagles in the juicy matchup of NFC division leaders is its evolving defense has underachieving Mark Sanchez to target at quarterback. No matter Sanchez had a prolific starting debut with the Eagles in their lopsided victory over the Carolina Panthers on Monday night, the Packers feel the former first-round draft pick who wore out his welcome with the New York Jets can be goaded into making mistakes by applying a good dose of pressure on him. Green Bay is among the league leaders with 18 takeaways, including 12 interceptions. And, the surefire way for the Packers to make sure the football is consistently staying in Sanchez’ right hand, rather than him handing the ball off with regularity to the dangerous halfback duo of LeSean McCoy and Darren Sproles against Green Bay’s 30th-ranked rush defense, is to jump out to a big lead early as they did in the last three home games.

To do so, expect the red-hot Aaron Rodgers (NFL record-tying six touchdown passes in the first half of the rout of the Bears last time out) to have the green light to continue throwing at will to the big-play likes of Jordy Nelson and Randall Cobb as well as halfback Eddie Lacy, who of late is doing more damage churning out yards on screens than he is rushing the football. The checkdowns could be vital for Rodgers to stay out of harm’s way from and shred the Eagles’ blitz-heavy scheme.

MATCHUPS TO WATCH

–Packers punt-coverage unit vs. Eagles returner Darren Sproles – The dynamic Sproles has been every bit the breakaway threat not only on offense but also on special teams when Philadelphia acquired the veteran running back in an offseason trade with the New Orleans Saints. Sproles leads the league with an average of 17.0 yards on punt returns. Two of those runbacks went for touchdowns, one for 82 yards and the other coming in the Monday night rout of the Panthers from 65 yards out. Led by the solid placement punting of Tim Masthay, the Packers rank fifth defending punt returns, yielding all of 5.9 yards per attempt. The longest runback by a Green Bay opponent this season is 13 yards.

–Packers offensive line vs. Eagles OLB Connor Barwin – The seemingly unstoppable Barwin leads the NFC with 10.5 sacks, only one short of his career high. Barwin is coming off a season-best output of 3.5 sacks at the expense of the Panthers on Monday.

“He’s really playing at a high level right now,” Eagles head coach Chip Kelly said Wednesday.

With Barwin’s ability to wreak havoc from the outside while lined up on both sides in Philadelphia’s 3-4 scheme as well as up the middle, all five linemen and extra blockers for Green Bay will be on high alert. The Packers didn’t allow a sack in their Sunday night clobbering of the Chicago Bears. It would be a monumental accomplishment if Green Bay can put up another zero against the Eagles’ high rate of pocket pressure, keyed by Barwin.
