The NFLPA and the National Football League have agreed to a memorandum of understanding to explore a merger.

The deal is a potential merger of both leagues into a single entity that would combine league revenue and revenues from the NFL’s 32 teams into a larger pool for NFLPA revenue, a source told Fox Sports.

It is the first step toward a merger in the 21st century.

The terms of the agreement are not public, but the deal is expected to be finalized on Tuesday.

A merger of two major sports leagues would be significant for the league, and would allow the NFL to gain a larger share of the total revenue generated by its teams.

It would also be a boost for the NFL in the coming years as it seeks to expand the league in new markets.

The NFL is seeking to expand its market to the U.S. with a proposal to move the Super Bowl to a neutral site in New Orleans.
