Short answer: no. Long answer:
61. What are the rules for retired players? What if the player suffers a career-ending injury?There's nothing binding about a player announcing his retirement. The player can still sign a new contract and continue playing (if he's not under contract), or return to his team (if he is still under contract) and resume his career.
The only exception to this is when a player is still under contract, wants to quit, and his team doesn't want to let him out of his contract. Under these circumstances the player can file for retirement with the league. The player is placed on the league's Voluntarily Retired list (see question number 77), forgoes his remaining salary, and cannot return to the league for one year. The latter requirement prevents players from using retirement as an underhanded way to change teams, and can be overridden with unanimous approval from all 30 teams. For example, guard Jason Williams signed with the LA Clippers in August 2008, then changed his mind the following month, announcing his retirement. He applied for reinstatement in early 2009, but his request was denied by a vote of 24-6. Williams later signed with the Orlando Magic once the one-year anniversary of his retirement announcement had passed.
Any money paid to a player is included in team salary, even if the player is no longer playing or has retired.
There is one exception whereby a player can continue to receive his salary, but the salary is excluded from team salary. This is when a player suffers a career-ending injury or illness. The team must waive the player, and can apply for this salary exclusion on the one-year anniversary of the last game in which the player played1. Only the player's team at the time the injury or illness was discovered (or reasonably should have been discovered) can apply for this salary exclusion.
The determination as to whether an injury or illness is career ending is made by a physician jointly selected by the league and players association. The determination is based on whether the injury or illness will prevent the player from playing for the remainder of his career, or if it is severe enough that continuing to play constitutes a medically unacceptable risk.
If the injury exclusion is granted, the player's salary is removed from the team salary effective:
If the player played 10 or more games1 that season, on the one-year anniversary of the player's last game.
If the player played fewer than 10 games1 that season, 60 days after his last game, or the one-year anniversary of his last game in the previous season, whichever is later.
If the player "proves the doctors wrong" and resumes his career, then his salary is returned to the team salary when he plays in his 25th game1 in any one season, for any team. This allows a player to attempt to resume his career without affecting his previous team unless his comeback is ultimately successful. If the 25th game was a playoff game, then the player's salary is returned to the cap effective on the date of the team's last regular season game (i.e., the returned salary counts toward the luxury tax).
There are a few additional nuances to the salary exclusion:
If the player resumes his career and his salary is returned to the team salary, the team can re-apply for the salary exclusion under the same rules (including the rules for the waiting period).
If a player retires, even for medical reasons, his team does not receive a salary cap exception to acquire a replacement player.
A team cannot apply for this salary exclusion if they have applied for a Disabled Player exception (see question number 25) that season, whether the exception was granted or not.
If this salary exclusion is granted, the team cannot re-sign or re-acquire the player at any time.
This salary exclusion can be used when a player dies while under contract.
