England have announced squads for the four-match tour of New Zealand next month and the game against the Barbarians.
Thirty players will fly to Auckland on Tuesday, May 27, and be available for the 1st Test at Eden Park on Saturday, June 7.
A further group will leave on Monday, June 2 following the Aviva Premiership final between Saracens and Northampton Saints (May 31) and the England XV v Barbarians match at Twickenham Stadium (June 1). These players will be named on the morning of Monday, June 2 (BST) following an assessment of both games.
"We are excited about the squad we are taking to New Zealand and, while there continues to be challenges in selection, we will be well and truly ready for the 1st Test," said England head coach Stuart Lancaster.
"It has a been good few days training and great to be able to work with a larger group of players in the lead up to the Barbarians game and the tour.
"With the Barbarians game and the Aviva Premiership final to come we will make our final selection once we know the availability of all players. This group will fly out on the Monday following the Barbarians game.
"As is often the case there are some players unavailable through injury and it is a shame that recently both George Ford (Bath) and Anthony Allen (Leicester Tigers) have had to withdraw due to shoulder and knee injuries sustained towards the end of the season
"Anthony Watson (Bath) is being treated for a hamstring injury and will continue his recovery in England before a final decision is made on whether he will join us in New Zealand on the Monday flight post-Aviva final and Barbarians game."
