The NFL's salary cap for this season has been set at $133 million US, the highest amount in league history.
Each team must be compliant with the cap number by March 11, when the league's free agency period begins. The cap amount announced Friday, which applies to active players' salaries, is up from $123 million last season and surpasses the previous high of $127,997,000 in 2009.
NFL teams can carry over unused salary cap room from the previous league year, and the NFLPA says in a release Friday that the average carryover for those teams that elected to do so was $6.1 million.
The league's salary cap is calculated by taking a percentage of all projected NFL revenues, subtracting projected benefits for the season, and dividing by 32 teams.
