Ok so from more details emerging it doesn't appear that Von is in Stage 3:
Players move to stage 3 if they have two positive tests when in stage 2 or one positive test to go with one instance when the player failed to comply with the program. The minimum suspension for a violation in stage 3 is a calendar year.
In Von's case the league wanted to suspend him for a year because he had a four game suspension from not providing a sample and possibly tampered with the sample gathering process (spilling, then diluting it).
So I don't believe he actually IS in stage 3.
