Leinster fly-half Ross Byrne has been ruled out of the upcoming United Rugby Championship game against Connacht due to an arm injury.
Byrne sustained the injury during the club's 21-16 victory over Munster last weekend as he attempted a tackle on Craig Casey.
He is now set to take an expert opinion on the extent of the damage but is certain to miss the upcoming clash against Connacht.
"Ross Byrne will have further examination for an arm injury picked up at the weekend but has been ruled out of selection this week," read a statement from the province.
"I don't know any specifics," scrum coach Robin McBryde told RTÉ Sport.
"It's just unfortunate for Ross really. The incumbent 10 really after Johnny [Sexton's retirement]. Just on his return he picks up an injury so I don't know the details but it must be very frustrating for him."
Leinster are at second place in the United Rugby Championship table with five wins from six matches.
