The 2021 NFL league year and trading period began on March 17. On March 15, teams were allowed to exercise options for 2021 on players with option clauses in their contracts, submit qualifying offers to their pending restricted free agents, and submit a Minimum Salary Tender to retain exclusive negotiating rights to their players with expiring 2020 contracts and fewer than three accrued seasons of free agent credit. Teams were required to be under the salary cap using the "top 51" definition (in which the 51 highest paid-players on the team's payroll must have a combined salary cap). On March 17, clubs were allowed to contact and begin contract negotiations with players whose contracts had expired and thus became unrestricted free agents.
The following notable trades were made during the 2021 league year:

The league introduced COVID-19 protocols intended to encourage vaccination among players, coaches, and staff. On July 22, the NFL warned teams that if a game cannot be rescheduled within the 18-week regular season schedule due to COVID-19 outbreaks among unvaccinated players, the team responsible for the outbreak would be charged with a loss by forfeit and be responsible for financial compensation to the other team, as normally players on both teams are not paid for canceled games. On July 24, it was reported that the league will fine players $14,650 for each violation of COVID-19 protocol if they are unvaccinated.
On July 23, the league announced the following temporary rules for 2020 would remain in place for 2021, allowing roster flexibility due to uncertainty regarding the pandemic.
A player on injured reserve could return after missing three games, instead of the normal eight.
Teams could return an unlimited number of players from injured reserve throughout the year, instead of the normal limit of three.
Practice squads could include up to 16 players for each team, up from 12.
After 4:00 p.m. ET on the Tuesday of a game week, a team could designate up to four practice squad players as "protected," meaning they are not allowed to sign with another team until after their current team plays its next game.
Up to two practice squad players could be elevated to the active roster each game week without removing any current players, 4:00 p.m. ET the day before a game.
On August 30, the league and the National Football League Players Association (NFLPA) agreed to COVID testing protocols for the season. Fully vaccinated players were tested at least once per week and could opt for additional testing. Like in 2020, unvaccinated players were tested every day during the regular season and postseason except game days.
Corresponding with the expansion of the regular season to 17 games, the preseason was reduced to three games per team. NFC teams each hosted two preseason games and AFC teams each hosted one. There was a league-wide bye week the weekend of September 4–5, between the final preseason game and the start of the regular season.
The NFL released its regular season schedule on May 12. The season was played over an 18-week schedule beginning on September 9. Each of the league's 32 teams plays 17 games, with one bye week for each team. The regular season concluded on January 9, 2022; all games during the final weekend were intra-division games, as it has been since 2010.
The 2020 collective bargaining agreement (CBA) signed by team owners and the NFLPA allowed for an expansion of the regular season from 16 to 17 games. On March 30, 2021, owners approved the expanded schedule. The extra game was added to the existing scheduling formula. Each team continues to play the other three teams in its own division twice, one game against each of the four teams from a division in its own conference, one game against each of the four teams from a division in the other conference, and one game against each of the remaining two teams in its conference that finished in the same position in their respective divisions the previous season (e.g., the team that finished fourth in its division would play all three other teams in its conference that also finished fourth in their divisions).
The added game is a fifth interconference matchup between divisions that had played each other two years earlier, based on the position in their respective divisions the previous season (e.g. the team that finished fourth in its division plays a club that finished fourth in a division of the other conference). AFC teams host the extra game in odd-numbered years, including 2021, with NFC teams getting the extra home game in even-numbered years.
