Charley Casserly just said on NFLN that he did his homework as he would when he was a GM in the league and confirmed that both Matthews and Cushing DID NOT test positive at the combine for steroids and PEDs. He said the way it works is this, the players would be notified if 1st if they failed a test, called sample A. If they then dispute it they are tested again, sample B, then the teams are notified 1 week before the draft if they test positive. He said the only person who would know at this point in time is Dr. Lombardo and his mouth is like a "vault," so any rumors out there are just that. He also said he dispises this type of internet reports because these people running those sites are responsible to no one, unlike himself who has to answer to his boss over at CBS. So, they have nothing to lose by putting out these rumours and everything to gain. IMO, they are also used by certain NFL people to create false reports about players so teams have to go back and do more work on a player, re-interview him, people around the player, etc.
