Q. When does the 2014 free agency signing period begin?

A. At 4:00 p.m. ET on Tuesday, March 11.

Q. What is permitted during the three-day negotiating period prior to the start of free agency?

A. Beginning at 12:00 noon ET on Saturday, March 8 and ending at 3:59:59 p.m. ET on Tuesday, March 11, clubs are permitted to contact, and enter into negotiations with, the certified agents of players who will become Unrestricted Free Agents upon the expiration of their 2013 player contracts at 4:00 p.m. ET on March 11. However, a contract cannot be executed with a new club until 4:00 p.m. ET on March 11.

During this negotiation period, a prospective unrestricted free agent cannot visit a club (other than the player's current club) at its permanent facility or at any other location, and no direct contact is permitted between the player and any employee or representative of a club (other than the player's current club). If a player is self-represented, clubs are prohibited from discussions with the player during the negotiating period.

Clubs (other than the player's current club) may not discuss or make any travel arrangements with prospective unrestricted free agent players, their certified agents, or anyone else associated with the player until the expiration of those players' 2013 Player Contracts at 4:00 p.m. ET on March 11.

The three-day negotiating period applies only to potential unrestricted free agents; it does not apply to players who are potential Exclusive Rights Players or Restricted Free Agents, or to players who have been designated as Franchise Players or Transition Players.

Q. What are the categories of free agency?

A. Players are either "Restricted Free Agents" or "Unrestricted Free Agents." A Restricted Free Agent may be subject to a qualifying offer. A Restricted or Unrestricted Free Agent may be designated by his prior club as its Franchise Player or Transition Player.

Q. What is the time period for free agency signings this year?

A. For Restricted Free Agents, from March 11 to May 2. For Unrestricted Free Agents who have received the June 1 tender from their prior club, from March 11 to July 22 (or the first scheduled day of the first NFL training camp, whichever is later). For Franchise Players, from March 11 until the Tuesday following the 10th week of the regular season, November 11. For Transition Players, from March 11 until July 22. If the above-listed players do not sign by November 11, they must sit out the season.

Q. What is the difference between a Restricted Free Agent and an Unrestricted Free Agent?

A. In the 2014 League Year, players with three accrued seasons become Restricted Free Agents when their contracts expire at the conclusion of the 2013 League Year. Unrestricted Free Agents have completed four or more accrued seasons. An Unrestricted Free Agent is free to sign with any club with no draft choice compensation owed to his old club.

Q. What constitutes an "Accrued Season"?

A. Six or more regular-season games on a club's active/inactive, reserved/injured or reserve/physically unable to perform lists.

Q. What could restrict the ability of a Restricted Free Agent to sign with a new club?

A. If he has received a "qualifying offer" (a salary tender predetermined by the Collective Bargaining Agreement between the league and its players) from his old club. He can negotiate with any club through May 2. If the Restricted Free Agent signs an offer sheet with a new club, his old club can match the offer and retain him because the qualifying offer entitles it to a "right of first refusal" on any offer sheet the player signs. If the old club does not match the offer, it may receive draft choice compensation depending on the amount of its qualifying offer. If an offer sheet is not executed on or before May 2, the player's negotiating rights revert exclusively to his old club. In addition, a player who would otherwise be a Restricted Free Agent may be designated by his old club as its Franchise Player or Transition Player. No Restricted Free Agents were designated as Franchise or Transition players this year.

Q. What determines an Unrestricted Free Agent?

A. A player with four or more accrued seasons whose contract has expired. He is free to sign with any club, with no draft choice compensation owed to his old club, through July 22 (or the first scheduled day of the first NFL training camp, whichever is later). At that point, his negotiating rights revert exclusively to his old club if by June 1 the old club tendered the player a one-year contract for 110 percent of his prior year's salary. His old club then has until the Tuesday following the 10th week of the regular season (November 11) to sign him. If he does not sign by that date, he must sit out the season. If no tender is offered by June 1, the player can be signed by any club at any time throughout the season.

Q. What is the salary cap for 2014?

A. The salary cap is $133,000,000 per club.

Q. When must teams be in compliance with the cap?

A. At the start of the 2014 League Year, which begins at 4:00 p.m. ET on March 11.

Q. If a team is under the salary cap at the end of a given season, can the team carry over room to the next season?

A. Yes. A team may "carry over" room from one League Year to the following League Year by submitting notice to the NFL prior to 4:00 p.m. ET on the day before the team's final regular-season game indicating the maximum amount of room that the club wishes to carry over.
