In 2015, Avenatti prevailed against the National Football League (NFL) following a jury trial in Dallas. He later pursued a class-action suit on behalf of fans who showed up for Super Bowl XLV with tickets that didn't correspond to actual seats but the courts in Texas declined to certify the class. Later, in 2016, Avenatti filed another class action lawsuit against the NFL, this time on behalf of ticket-holders to the annual Hall of Fame Game, which was cancelled a few hours before kickoff.
