Tom Pelissero and Rubie Edmondson | USA TODAY Sports

The NFL salary cap for this season is $123 million per team, though most teams have more space available, thanks to carryover of unused space from 2012 and other adjustments. The above photo gallery is a breakdown of each team's cap as of Wednesday (Sept. 12) and a percentage look at how they've allocated their space by position. (Note: some transactions completed this week may not be reflected in these numbers.)

Abbreviations include:

"ST" for special teams, "DB" for defensive backs, "LB" for linebackers, "DL" for defensive linemen, "OL" for offensive linemen, "TE" for tight ends, "WR" for wide receivers, "RB" for running backs, "QB" for quarterbacks and "Space" for room under the salary. "Dead" stands for dead money – guaranteed payments owed to players no longer on the roster, bonus proration that had not been applied to the cap before a player was cut, etc.
