Proskauer Rose on Monday said it had elected Joseph M. Leccese, 49, as its new chairman. Leccese will succeed Allen I. Fagin, 60, who has held the position since 2005. Fagin will step down in January after serving the maximum six-year term as chair.

A native New Yorker and graduate of the University of Virginia Law School, Leccese joined Proskauer in 1986 as an associate. As a partner in the corporate department and co-head of its sports law group, Leccese counts among his clients several major sports leagues, including the National Basketball Association, National Hockey League and Major League Soccer. He represented Jeffrey Lurie in his acquisition of the Philadelphia Eagles and Robert Wood Johnson IV when he bought the New York Jets for $635 million. Leccese also represents banks and bond insurers in transactions involving sports properties and was involved in the bond financing for Citi Field.
