There's a limit on how many games can be flexed to Thursday Night Football in a season, and the NFL may hit the limit after the latest rule change

NFL teams reportedly may have less advance notice when their games are going to be flexed from Sunday to Thursday following Monday's vote at the league meetings.

The NFL has approved a rule-change resolution to reduce the amount of time required to flex a Sunday game onto Thursday Night Football, according to a report.

Per a report from Tom Pelissero of NFL Media, at least 24 teams voted in favor of a resolution that will allow the league to flex games from Sunday to Thursday night with 21 days notice. The window for a flex was 28 days when the league approved flexing games to Thursday two years ago and that remained the window last season.

The vote will address changing the amount of time teams get for flexing Thursday games from 28 days to 21 days, per Sports Business Journal. NFL owners will be asked to vote this week on a measure that would potentially give teams one less week’s notice if a scheduled “Thursday Night Football” game gets swapped out for a better matchup.

The NFL is considering switching games from Sunday to Thursday with only three weeks' notice. Owners will vote today on a measure that would change the league’s flexible scheduling rules, according to Ben Fischer of Sports Business Journal.
