Former NFL coaches Rex and Rob Ryan appeared to get into an altercation at a bar in Nashville on Sunday.

Twitter user Cooper Stefaniak shared two videos in which two men resembling the Ryan brothers are involved in a scuffle with bar patrons:

Earlier in the day, the Pittsburgh Post-Gazette's Sean Gentille reported the Ryan brothers were interacting with fans at Margaritaville in downtown Nashville:

On Saturday, the Ryans took part in pregame festivities ahead of the Nashville Predators' Game 3 victory over the Pittsburgh Penguins in the 2017 Stanley Cup Final. NHL on NBC posted a video of Rex smashing a Penguin-themed car outside Bridgestone Arena:

Rex and Rob most recently worked together on the Buffalo Bills' staff. Rex was the head coach for the past two years, while Rob was the assistant head coach for defense in 2016.

The Bills fired the pair on Dec. 27 after the team scuffled to a 7-8 record.
