"It's Always Sunny In Philadelphia" star Rob McElhenney wasn't gonna let a silly awards show get in the way of watching his beloved Eagles' playoff matchup against the Tampa Bay Buccaneers on Monday ... 'cause the actor tuned in to the game from his phone in the middle of the ceremony.

Rob's costar and wife Kaitlin Olson captured the scene in a selfie posted to social media ... with a caption that read, "Who schedules the Emmys the same night as the @eagles #gobirds #FlyEaglesFly."

Unfortunately for Rob, the action on the field wasn't a pleasant experience ... as Baker Mayfield led the Bucs to the 32-9 upset win, booting the reigning NFC champs out of the postseason.

The game also had to be a big bummer for Rob, as it appears to be the last one of future Hall of Famer Jason Kelce's stellar career.

While the Eagles won't bring home the Lombardi Trophy in 2024, at least Rob was able to snag some hardware this awards season -- his "Welcome to Wrexham" show received five Emmys off six nominations.

As for 'Sunny,' the gang took the stage to present during the event ... and took the opportunity to bash the fact the show hasn't been nominated in its 16 years on the air -- despite its massive popularity.
