Devin Toner has been ruled out of the Guinness Pro 14 final, but Leinster say they don't believe it is a long-term injury for the Meath man.
The towering lock was replaced in the second half of the 24-9 semi-final victory over Munster at the RDS after falling awkwardly.
As expected, he will not feature against Glasgow Warriors this weekend, but whether the injury is a genuine concern for the World Cup remains to be seen.
Leinster said the 32-year-old is to have "further assessment" on the injury, while Felipe Contepomi confirmed that they are still awaiting MRI results.
"We’d like to think it’s not a long-term injury, but we still don’t have the test results," he said.
Elsewhere flanker Josh van der Flier came through unscathed following his return to action at the weekend, while Joe Tomane, Barry Daly, Mick Kearney, Dan Leavy and Adam Byrne all remain sidelined with long-term injuries.
