Ireland, Scotland, England and Wales have all now announced their final squads for this year's Rugby World Cup.
All four chose to leave some high profile players out with Wales' head coach Warren Gatland deciding against taking newly capped fly half Gareth Anscombe in his final 31.
Scotland boss Vern has chosen to leave out Scotland's most capped player Dougie Fife and Ireland's head coach Joe Schmidt has been forced to leave out flanker Tommy O'Donnell after an injury during a warm-up game.
England announced their squad last week and made a controversial decision to include rugby league convert Sam Burgess, who had only made his England debut a few weeks ago.
