lewsey puzzle over disallowed try england s josh lewsey has claimed he was denied a late try in his side s six nations loss to ireland.  the wasps wing insisted he grounded the ball when he was bundled over the line and said referee jonathan kaplan had made a wrong decision.  i m positive i touched the ball down over the line   lewsey told bbc sport.  it certainly wasn t a turnover.  i was driven over and i put the ball on the ground. the whistle went and i let go of the ball.  lewsey added:  one of the irish players scooped it back after the whistle and to our surprise the referee then gave a turnover.  as far as i m concerned  that incident and mark cueto s effort from charlie hodgson s cross-field kick that led to what looked like a good try were the two key elements in the game.   cueto was also puzzled as to why his try had been disallowed by kaplan.  i don t think i could have been offside for  without a doubt  i was behind the ball   said the sale player.  the move was a planned technique  it was not off the cuff. we rehearse it time and time again.  i wouldn t say we were robbed  some decisions go with you and some go against you. today they went against us and that s tough at international level.
