Jason Kelce’s NFL career is over.

The Philadelphia Eagles superstar just revealed he’s officially retiring … saying at an emotional news conference Monday afternoon he’s done.

Jason cried while making the announcement … in fact, tears streamed down his face even before he began speaking at the event. Several times during his speech, he needed breaks to compose himself.

Plenty of family and friends turned out to watch the 36-year-old center say goodbye … including Travis Kelce, who was also emotional as his big bro addressed the crowd.

Throughout his speech, Jason thanked a ton of people — namely coaches and ex-teammates. He also referenced losing the Super Bowl to Travis.

Jason talked about meeting his wife, Kylie, as well. And, he drew some big laughs, too, when he talked about Nick Foles’ “big d***” and Darren Sproles’ “4-foot-8” height.
