Coach Mike Shanahan and the Redskins will have a bit more salary cap flexibility with the cap being set higher than originally projected (John McDonnell/The Washington Post)

The NFL’s salary cap for the 2013 season has been set at $123 million per team, according to a person familiar with the situation.

That is higher than the original estimate of about $121 million per team. The higher figure helps teams such as the Redskins, who will have to make moves to get under the cap unless they are successful in overturning the $18 million salary cap penalty they are scheduled to absorb this year.

Agents were informed by the NFL Players Association that the 32 teams league-wide collectively carried over more than $200 million in unused salary cap space from last year to this year, as cap rules permit.

NFL teams must be in compliance with the salary cap when the new league year begins March 12.

That also is when the NFL free agent market is scheduled to open.
