Less than a month after Gibson, Dunn & Crutcher formally unveiled its sports law practice, partner Andrew Tulumello is teaming up with Winston & Strawn’s Jeffrey Kessler to try to contain the fallout from the National Football League’s “Deflategate” fiasco.

Washington, D.C.-based Tulumello, a class action defense specialist, braved mobs of fans and reporters to join Kessler at NFL headquarters in New York Tuesday morning to contest the four-game suspension of New England Patriots quarterback Tom Brady. The pair appeared before commissioner Roger Goodell, who is hearing Brady’s appeal despite calls by the NFL Players Association for a neutral arbitrator to decide Brady’s fate. By Tuesday evening the hearing had yet to adjourn.
