The National Football League Players Association said it was opposed to any deal that does not include a collective bargaining agreement.
The league has been negotiating a deal with the players’ union for the past two years.
It has yet to reach an agreement with the union, but league officials have said a deal is close.
NFLPA President DeMaurice Smith said in a statement Friday that “any proposed contract that does away with the bargaining process is unacceptable.”
“We are hopeful that this week’s events will provide the impetus for a successful and fair negotiations,” he said.
“Any proposal that does that is not good for the NFL and bad for the game.”
The union wants the NFL to end lockout conditions and allow teams to continue playing.
Smith also said the players have been negotiating with the league about a new CBA, but “no deal is being finalized.”
NFL spokesman Brian McCarthy said Friday that the league will not comment on pending negotiations.
