SAN ANTONIO — Just one year in and the Alliance of American Football could be looking to throw in the towel.

The league's majority owner, Tom Dundon told USA TODAY Sports, that lack of cooperation from the NFL Players' Association to use young players from NFL rosters has left the future of the league unclear.

The AAF, Dundon reiterated to USA TODAY Sports, is a developmental league and without young players from the players union to develop, they may have to discontinue the league.

While the NFLPA did not have an official response to the lack of cooperation accusation, a players' union official told the publication that there are risks when it comes to lending active NFL players to the AAF.
