surely a medical for a signing includes all sorts of scans and ECG's while a fitness test for a match would not be as thorough

Surely if someone has been out for a year with serious injury then the specialist/physio treating them would want to be 100% happy before allowing them to return to training/competition.

Its just all a bit odd that we passed him fit yet Hull FC have uncovered the fact that he isn't over the injury.

Actions speak louder than words. For example, a press release stating Alan Langer has been released due to a career-ending ankle injury means nothing when he is playing State of Origin the following season.
A statement that Reardon is nearing fitness doesn't mean much when the fact is Reardon actually hadn't played for us since his injury at any level including reserves, which is maybe a fairer indication as to his medical assessment by Warrington than a stock comment from Lowes in the middle of the court hearings when Warrington were keeping comments to a minimum as they awaited the outcome of his trial.
Whatever words might have been said, we released him without him playing a game this season, and so to criticise the club for passing him fit is ridiculous.

Maybe the real question you should ask is why Hull announced a signing, with all the related bad press that they knew it would bring without even giving him a medical, and in fact apparently waited 11 days (until the day before he was due to be sentenced) to do so?

*** **** had a broken back but then went on Gladiators

if he hasn't played since may last year, and by my reckoning, thats approaching a year, would we not have been in a similar situation to the one bradford found themselves in with tame tupou, so could we have not gotten rid that way?
