Leinster are sweating on the availability of a number of front-line players ahead of Saturday's Investec Champions Cup clash with Leicester.
Ireland internationals Robbie Henshaw, Garry Ringrose, Andrew Porter, Ciarán Frawley and Hugo Keenan feature in a lengthy injury update issued by Leo Cullen today, with the province saying all will be assessed further this week.
The four-time European champions host the Tigers at the Aviva Stadium on Saturday evening (8pm, live on RTÉ2 and RTÉ Player) in a round of 16 tie.
Centre Henshaw came off for a head injury assessment in the 51st minute of his team's impressive 47-14 BKT URC win over Bulls on Friday night.
The 30-year-old is following the return-to-play protocols, as is scrum-half Luke McGrath who was yellow carded for a high tackle on Kurt-Lee Arendse in the first half.
"They've both got different return-to-play protocols that they are going through now," said assistant coach Andrew Goodman. "Pretty confident they'll check those off...as they go through the week."
Asked about the tackle technique that led to both players' injuries, Goodman said that Leinster have been focusing on going low this season.
"To be honest, the change in mindset [this season] is to be lower," said the New Zealander.
"Those were a couple of ones that have just slipped out, the boys understood there should have been more of a level change there.
"Jacques [Nienaber, senior coach is] really driving the low tackle focus to avoid cards, and to get people on the floor as well."
Centre Ringrose (shoulder) and prop Porter (shoulder) also face further fitness tests having last played for Ireland in their final Six Nations game against Scotland on 16 March.
Full-back Keenan (hip) was a late withdrawal from that game and, alongside utility back Frawley (foot), will be given until later in the week to recover.
"They've gone through bibs today so it's just how they turn up tomorrow. They are all in consideration for the week ahead," added Goodman, who will join the Ireland set-up at the end of the season as backs coach.
Ireland back Jimmy O'Brien, who was injured prior to the Six Nations is nearing a return from a neck issue, while centre Charles Ngatai is to step up his recovery from a calf injury.
Scrum-half Cormac Foley is back in contention after a shoulder injury, while there were no further updates on James Ryan (arm), Tommy O'Brien (hamstring) and Alex Soroka (foot).
