1.5 Intervention Stages
1.5.1 Stage One
Testing: In Stage One, the Medical Director may, in his discretion, require a Player to submit to testing for Substances of Abuse
as often as is required to evaluate the Player adequately...
(c) Discipline
If the Medical Director, after consultation with the Medical Advisor, determines that a Player in Stage One has failed to cooperate with the evaluation process or fails to comply with his Treatment Plan, the NFL Management Council and the NFLPA shall be notified and the Player
will be subject to a fine equal to two-seventeenths (2/17) of the Paragraph 5 amount in his NFL Contract, and he will be advanced to Stage Two...
1.5.2 Stage Two
Testing: All Players in Stage Two
will be subject to unannounced testing subject to the terms of this Policy. At the sole discretion of the Medical Advisor, a Player may or may not be tested; however, if he is tested, he may not be tested more than ten (10) times during any calendar month.
(b) Duration
A Player
will remain in Stage Two until such time as he is discharged by the Medical Director following assessment and determination. Such determination shall be based on the Medical Director’s professional judgment regarding the Player’s compliance with the Program, clinical progress and negative testing record.
(c) Discipline
A Player in Stage Two who violates the Policy will be subject to discipline by the Commissioner as set forth below:
Failure to Cooperate with Testing or Clinical Care
1st Violation: 1-week’s salary
2nd Violation: 2-weeks’ salary
3rd Violation: 3-weeks’ salary
4th Violation: 3-game suspension
5th Violation: 4-game suspension
6th Violation: 8-game suspension
7th Violation: banishment for an indefinite period of at least one calendar year
_________________
Stage Two players can be tested up to ten times per month. It may seem excessive to anyone other than the player and Medical Advisor but it is policy.
My question is where did the FIVE game suspension come from? Or has Collins' suspension since been clarified as either a 4-game or 8-game suspension? Those are the only discipline tiers for suspension above and below a "5-game suspension."
