The NFL and its players union have agreed to a record salary cap of $167 million per team for 2017, a person with knowledge of the number told USA TODAY Sports on Wednesday morning.

The person spoke on condition of anonymity because the number hadn’t been released publicly.

It falls within the range of $166 million to $170 million the league gave to teams in December and represents a fourth consecutive jump of at least $10 million — up from $155.27 million last season and $123 million back in 2013. That’s a more than 35% rise over the past four years.

The cap number doesn’t include roughly $37 million per team in player benefits. And it only begins to illustrate teams’ spending power when the 2017 league year begins March 9.

Teams carried over an average of more than $9.1 million in unused cap space from 2016, led by the Cleveland Browns ($50.1 million), Jacksonville Jaguars ($39.3 million) and San Francisco 49ers ($38.7 million). Pending possible contract extensions, the Browns are poised to enter free agency with more than $100 million in cap room. Average cap space per team is around $37 million.

The 2017 league year represents the start of another four-year window in which teams must spend a minimum of 89% of the cap in cash. All 32 teams met the 89% threshold for 2013 to ’16, with the Oakland Raiders the last to do so.

Under the 2011 collective bargaining agreement, players are guaranteed 47% of “total revenue” over the life of the deal, drawing from three streams: TV deals (55%), league properties (45%) and local revenue (40%).
