Section 5. Active List: If a player on the Practice Squad of one club (Club A) signs an NFL Player Contract
with another club (Club B), (1) the player shall receive three weeks salary of his NFL Player Contract at the 53-
player Active/Inactive List minimum even if he is terminated by Club B prior to earning that amount, and
(2)
Club B is required to count the player on its 53-player Active/Inactive List for three games (a bye week counts
as a game) even if he is terminated or assigned via waivers to another club or is signed as a free agent to another club’s 53-player roster or another club’s Practice Squad prior to that time. If the player is terminated from Club
B’s 53-player roster and signed to Club B’s Practice Squad, he shall continue to count on the club’s 53-player

signed to Club B’s Practice Squad or is signed or assigned to another club’s 53-player roster or Practice Squad,
any salary (as that term is defined in Article XXIV, Section 1(c)) that he receives from any NFL club applicable
to the three-game period shall be an offset against the three weeks salary that he is entitled to receive from Club
