Sylvester Stallone posted a video Monday voicing his support for the Philadelphia Eagles ahead of Super Bowl LII.

Wearing a custom jersey and an Eagles ring, Stallone called himself a “diehard fan” and shared memories about former Eagles running back Timmy Brown— Stallone’s favorite Eagle.

“Birds of a feather fly together and we are going to soar this weekend! Go Eagles!” Stallone wrote.

The Eagles will face the New England Patriots on Feb. 4 at Minneapolis’ U.S. Bank Stadium.
