The sabbatical came about after persistent injuries which culminated in a serious long term ankle injury costing him a Lions place in 2009.
Since he has come back with Saracens the only rugby he has missed due to off field stuff was the Blues incident which was a ridiculous and hypocritical situation given that they the same club kept two players on an assault charge, didn't bother Jamie Roberts or Bradley Davies when they went about fighting in pubs, and proceeded to sign a player who had recently ****** in a Italian taxi.
So I don't regard him as fully to blame on that part as there was something strange going on with the coaches there. And that was 1 month missed through an off field incident, hardly much in comparison to all the injuries.
And look as Henjak's past record as well ...
He was injured loads at London Welsh too by the way Draggs, even though he did well when he was fit.
