A Phillies chant inside Lincoln Financial Field? Inconceivable until today, but there it was, right after Brian Westbrook sealed the Eagles' 27-14 win over the Atlanta Falcons with a 39-yard run into the end zone. You would have thought those die-hard fans who hadn't prematurely left the building with just under eight minutes to play would have broken out into this city's autumn anthem.

But there was no "E-A-G-L-E-S, Eagles!" cheer. Instead, it was "Let's go Phil-lies." During an Eagles game. Inside the Eagles' house.

Somewhere Joe Banner had to be choking on his saliva (or, at least, calling another local media outlet to complain about the unbalanced coverage this week).

It's all Phillies all the time these days, for good reason, and that even includes the day of the week typically reserved for the local football team.

There was more red in the Linc than any color other than green or black, and it wasn't in support of the Falcons. It seemed every other fan had on an Eagles jersey with a red Phillies cap. There there was a smattering of fans wearing Ryan Howard or Chase Utley jerseys with an Eagles lid.

The thing is, there was visible support for both Philadelphia teams, which isn't usually the case at the Linc for Eagles games. There might be a few Phillies hats in the crowd on a typical October Sunday, but thousands? No way.

It was bizarre, and given the ultra-competitive environment between the franchises, it had to drive those who dedicate their lives to running the Eagles crazy.

At least the Eagles won.

Jeffrey Lurie, a lifelong Boston Red Sox fan, told me before the game that he was pulling for the Phils. He attended Saturday night's marathon game with his son - though they left before it was over - and said he was optimistic the Phillies would win the Series.

"The Red Sox have won it enough," Lurie said. "My attitude is, most of the Phillies fans are Eagles fans, and I want the Eagles fans to get a championship however" they can.

Spoken like a true transplant. I'm pretty sure not everyone inside the NovaCare Complex feels the same way.

Consider Oct. 5. On that Sunday, the Eagles played Washington at the same time the Phils played Milwaukee in an elimination game in the NL division series. When Pat Burrell hit a three-run homer in the third inning, the Eagles, who led the Redskins by 14-0 at the time, flashed the score on their out-of-town scoreboard.

It was the last time they did that. As Jason Campbell took one last knee to seal Washington's comeback win, the Phillies finished off the Brewers to move on to the NL Championship Series. The Eagles and Phillies games ended within a minute of each other, crushing timing for the Eagles, whose fans left angry at one loss and enraptured by one win.

Today, the only time the Eagles officially acknowledged the Phillies inside the Linc was in a fourth-quarter announcement asking fans to exit the parking lots once the game ended to make way for the onslaught of Phillies fans heading to the ballpark. The Eagles also posted the message on the end-zone scoreboards, with a tiny "Good luck Phillies" at the end.

The fans booed in response to the parking-lot request. No one already parked at the sports complex for the Eagles game seemed particularly eager to skip out on the party brewing across the street.

On Saturday, the Flyers moved the starting time of their game against the Devils up to 4 p.m. so fans would not have to choose between their game and the World Series. They also handed out rally towels with the Flyers' logo on one side and the Phillies' logo on the other.

The 76ers, likewise, announced last week that they would move up the start of their home opener by an hour Wednesday if the Series were still going on.

The Eagles could have said something at the Linc today. They could have posted "Let's go Phillies" on the end-zone boards before kickoff, and the place would have gone nuts. It would not have detracted from the atmosphere, and perhaps it would have given the Eagles players an extra jolt heading into what turned out to be a boring first half.

It's almost as if the Eagles have been afraid to acknowledge the Phillies' success for fear of losing their own cachet, as if the Phillies' success would somehow shorten the Eagles season-ticket waiting list.

The waiting list for a championship is equally long, and maybe that's all this is. Every team in this town wants to be the one to break the 25-year drought. The Phillies, at the moment, are the closest. The Eagles, Sixers and Flyers have had their chances.

Still, it was surreal hearing a Phillies chant inside the Eagles' house, and I'm sure I wasn't the only one who noticed.
