Sylvester Stallone is all in on the Philadelphia Eagles, and he’s making it very clear on Instagram.

From the NFC Championship Game through Saturday, the actor has posted about his Eagles fandom six times. His most recent posts have been photoshops showing boxers in Patriots and Eagles helmets.

One of them is of a photoshop of Rocky Balboa and Ivan Drago with the caption:

We Know how this one turned out ….. We know who’s going to win the Super bowl …. UNDERDOG TO TOPDOG! #flyeaglesfly #philly #rockybalboa #strength #agentnickyc #superbowl

The other is the iconic photo of Muhammad Ali standing over Sonny Liston with football helmets added. As you can see, Ali is in the Eagles helmet.

“The bigger they are the harder they fall!” #FlyEaglesFly

Here are the other IG posts:

In this one that Stallone shared on the day of the AFC Championship Game, he explains that he has been an Eagles fan ever since he was a teenager.

Stallone says he has “tremendous respect for Tom Brady and the Patriots, but … EAGLES BY KNOCKOUT!!!” He also tosses in a quote from the Rocky Balboa movie.
