NFLPA investigating Vincent's e-mail

The NFL Players Association has retained a lawyer to determine whether one of its leading candidates to become executive director -- Troy Vincent -- revealed confidential information about player agents.

"Counsel is also investigating what if anything was done with any personal information that may have been transmitted," the union said in a statement released Tuesday.

The union has retained Joseph Yablonski, who has worked with the NFLPA as an outside counsel in the past.

SI.com first reported the allegations last week.

Vincent is one of three finalists to replace Gene Upshaw, who died in August.

The other candidates are former NFLPA president and current agent Trace Armstrong and Washington D.C.-based lawyer DeMaurice Smith.

The union's new leader will be selected by vote at the NFLPA's annual general meeting in Hawaii next month.
