Nick Sirianni is receiving his first taste of a bitter NFC East rivalry — relishing to the first-year Philadelphia Eagles head coach.

Who showed up to his Thursday press conference clad in a “Beat Dallas” shirt, four days before the teams do battle on Monday Night Football at AT&T Stadium.

Bulletin-board be damned.

“I really love the fact that I’m able to partake in this rivalry and it means a lot to the city, to our team; it means a lot to this building,” Sirianni proclaimed to reporters, via Tim McManus of ESPN.com.

“I’ll be wearing this all week. My kids got it, my wife has one. And, yeah, we’ll be wearing them.”

He added of the Cowboys: “I’m sure they’re going to have the picture of this shirt on there. And that’s fine. With the rivalry and it being a division game, I don’t know if anyone needs — our side, their side — needs any more bulletin board material or if it’s even going to help, because we know how big the rivalry is and how much it means to both sides.”

Monday’s matchup will mark the 125th meeting between the Eagles (1-1) and Cowboys (1-1), who lead the all-time series, 70-54. The sides split last season, with Dallas trouncing Philadelphia in the penultimate 2020 contest.
