Let's face it - all we know is:
(1) It's not something that the police are involved with, cos it would be public knowledge.
(2) He hasn't failed an official drugs test, reason - see above.
(3) On A.N.Other forum League Express editor Martyn Sadler has posted that he does know the reason and that the club's action is completely justified.

A quick question to the experts here on the VT in the field of drugs and mental health issues (in particular the Wakey fans) - why has it taken so long to sentence Adam Walker ? His alleged misdemeanor was well before Zak's and the same time as Rangi Chase who has been handed a two year ban. What's the hold up ?

Of only he had the presence of mind to claim that he could not take the test because he thought that the water provided could have been tampered with.

Less quick-witted than Ryan Bailey? Gosh.

"in particular the Wakey fans" - oh aye, cause we are privy to each and every anti doping case.

if you think we'd don't expect Adam Walker to get the same treatment whenever that it, you'd be wrong.

And unlike Cas fans, we don't excuse players when they make monumental stupid decisions of their own making.
