N.F.L. owners are prepared to end a small sliver of revenue sharing that helps shore up the league’s lowest-revenue teams.

The owners informed the players union that starting with the next league year in March — which would be the start of an uncapped season if no new collective bargaining agreement is reached — owners will not share a $100 million fund. Nine teams at the bottom of the revenue pecking order drew from that pool this season.

The $100 million represents a tiny fraction of the $6.5 billion — much of it money generated from television contracts — that all 32 teams share. The decision was first reported by ESPN on Sunday.
