Contract terminations A team and player may mutually agree to terminate a player's contract at any time. All players must clear waivers before having a contract terminated.

Buyouts can only occur at specific times of the year. For more details on contract terminations as buyouts:

Teams may buy out player contracts (after the conclusion of a season) for a portion of the remaining value of the contract, paid over a period of twice the remaining length of the contract. This reduced number and extended period is applied to the cap hit as well. If the player was under the age of 26 at the time of the buyout the player's pay and cap hit will reduced by a factor of 2/3 over the extended period. If the player was 26 or older at the time of the buyout the player's pay and cap hit will reduced by a factor of 1/3 over the extended period. If the player was 35 or older at the time of signing the contract the player's pay will be reduced by a factor of 1/3, but the cap hit will not be reduced over the extended period.

Injured players cannot be bought out.
