The Patriots say staff members used the term "deflate" to talk about losing weight — not about breaking the NFL's rules on football inflation, as the league says.
The NFL Players Association, which filed the appeal on behalf of the New England Patriots quarterback, is calling for a neutral arbitrator to hear the appeal.
The Patriots quarterback was recently suspended for his apparent role in underinflating game balls. For commentator Frank Deford, "Deflategate" is as much about Brady's vanity as it is about victory.
The move applies only to the league office. The National Football League's 32 teams already pay taxes on their profits, salaries and merchandise sales.
It would be the former Heisman winner's fourth NFL team. The New York Jets released Tebow in the spring of 2013; later that same year, he was cut by the New England Patriots.
Confirming a long-anticipated move, the NFL has hired its first female official on a full-time basis. She has spent nearly a decade working her way through the ranks in the NCAA.
Sarah Thomas has officiated football games in the NCAA and for the NFL's preseason and training camps. For the 2015 NFL season, she'll reportedly work full time at the game's highest level.
