Saracens' loss was Warren Gatland's gain as the Lions boss welcomed the men from Allianz Park to the tourist's training base in Maynooth, Ireland.
Owen Farrell, Maro Itoje and Co narrowly lost out to Exeter Chiefs in the Aviva Premiership semifinal, freeing them up to join their new teammates.
Mako Vunipola, George Kruis and Jamie George were the other Sarries men to be put through their paces under the watchful eye of Gatland.
With less than two weeks remaining before the first game of the tour, it is imperative the tourists gel as quickly as possible. It seemed that most of the work on a sunny afternoon in the East of Ireland was fitness-led, with the players engaging in a number of shuttle runs.
Wales flanker Sam Warburton has not played since suffering a knee injury early last month, but he is firmly on course to potentially lead the Lions in next week's tour opener against a Provincial Barbarians XV.
