The squad are based in Wales this week
With the first match less than three weeks away, the Lions have entered their training camp ahead of the tour to New Zealand.
Many of the squad are still unavailable due to club commitments, but the remaining members of the 41-man squad began preparations on Monday morning in Wales.
The squad are training in Wales' National Centre of Excellence, before a second camp in Ireland. The squad will fly to New Zealand later this month.
Players from the likes of Munster, Leinster, Wasp and Saracens are remaining with their clubs as the PRO12 and Premiership semi-finals take place this weekend. They will join the camp in the coming weeks.
Ulster's Rory Best, Jared Payne and Iain Henderson were the only Irish players in attendance. They were joined by players such as Stuart Hogg, Joe Marler, Ben Te'o and Taulupe Faletau.
The Lions first match takes place on June 3rd against the New Zealand Barbarians, with the First Test happening three weeks later on June 24th.
