Leinster Rugby head coach Leo Cullen has issued an injury update following Friday's Guinness PRO12 semi-final defeat to Scarlets.
Centre Garry Ringrose took a knock to his knee late in the game but it is not thought to be a major concern at this stage.
Both scrum-half Luke McGrath and back-row Rhys Ruddock were removed for a head injury assessment during the game and did not return to play.
The pair have entered the return-to-play protocols this week while all three will be assessed further by the Ireland medical team next week.
The trio are in Ireland head coach Joe Schmidt's 32-man squad for the summer tour of the USA and Japan which increased with the addition of Connacht's Quinn Roux.
British & Irish Lions Head Coach Warren Gatland is due to give an injury update on his squad later this afternoon and there are concerns over some of the five Leinster players included.
Prop Jack McGrath is the biggest concern after he injured his arm in the Scarlets game while Sean O'Brien was forced out of the match with a calf issue, following a number of weeks on the sidelines with a hamstring injury.
Outhalf Johnny Sexton was treated for a knock during the RDS defeat on Friday but Cullen said after the game he was fine as was prop Tadhg Furlong who only left the field due to cramp.
