The NFL Players Association is considering the proposed new collective bargaining agreement, which includes a 17-game season, according to Mark Maske of The Washington Post.
The players' association hasn't yet voted on the proposal, and few have spoken publicly on the matter.
However, Arizona Cardinals owner Michael Bidwill lent his support Wednesday to the idea of an expanded schedule.
"I think our fans would like more," Bidwill said on Arizona Sports 98.7 FM, according to team writer Darren Urban.
He added: "We have surveyed our fans. The health and safety data plays out that we can do 17 games and it's not going to impact the safety and the health of the players. I am really proud of the work the league is doing in terms of the health and safety. A lot of big strides have been made. ... We'll see where the players land."
A new CBA would first need to be approved by two-thirds of the NFLPA player reps. It would then go to a vote by all NFL players, from which a majority in favor is required to ratify the agreement.
The current CBA expires after the 2020 season
