Ireland full-back Jordan Larmour will miss the conclusion of the Six Nations and the Autumn Nations Cup after suffering a dislocated shoulder.
Larmour will undergo surgery this week, having sustained the injury in Leinster's Pro14 win at Benetton Rugby on Saturday.
The versatile 23-year-old will not be available to Andy Farrell for the Six Nations encounter with Italy at the Aviva Stadium on October 24 nor the final match of the tournament against France at Stade de France seven days later.
Larmour has also been ruled out of the internationals against Wales, England and Georgia next month.
Leinster on Monday stated that no timeframe had been put on a potential return for the influential Larmour.
Ryan Baird will be assessed this week after the lock suffered an adductor strain in the victory at the weekend.
