Swagger, the beloved, 145-pound bullmastiff who has been with the Browns since 2014, will make his final run onto the field Sunday at FirstEnergy Stadium. 

The pre-game tradition, though, isn't going anywhere, and it's staying in the family.

SJ, who will turn 11 months old Sunday, will be introduced to fans, during a brief, in-game moment during Sunday's third quarter. SJ will take over all of Swagger's duties starting Nov. 10, when the Browns host the Bills. Swagger will serve as the Dawg Pound Captain for his final game.

"Swagger has been a huge part of our team since 2014 and our fans absolutely love him," said Carlos Oseguera, Browns Senior Director, Fan Experience & Special Events. "Between his event appearances, pre-game duties on Dawg Pound Drive and his running out of the home team tunnel on game days, he's been the utmost professional through his years of service. We wish Swagger a happy retirement and know that SJ will carry on the family tradition beginning November 10."

Swagger has run through the tunnel at every Browns game at FirstEnergy Stadium since 2014. The lone "home" game he's missed was in 2017, when Cleveland faced the Minnesota Vikings in London. Swagger's British cousin, Otto, filled in for him to maintain the team's tradition in an overseas venue.

On top of running through the tunnel, SJ, who has already earned his American Kennel Club Canine Good Citizen badge, will follow in Swagger's paw steps by making regular appearances on Dawg Pound Drive before games and events throughout the community.  

Like Swagger, SJ hails from FD Farms in Rootstown, Ohio. Fred and Debby McLaughlin are the operators, and their son, Justin, is the dog's handler who will continue to run alongside him onto the field.
