NFLPA investigating Vincent over e-mail

The NFL Players Association has retained a lawyer to determine whether one of its leading candidates to become executive director - former Eagle 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 yesterday.

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 a finalist to replace Gene Upshaw, who died in August. The union's new leader will be selected by vote next month.
