Ankle injury rules Joey Carbery out of Ireland's games in Japan

Joey Carbery made his first start for Ireland in the match against the USA Eagles in New Jersey

Leinster fly-half Joey Carbery has been ruled out of Ireland's two Tests in Japan because of an ankle injury.

The 21-year-old was injured during Saturday's 55-19 win over the USA Eagles in New Jersey.

Ulster's Paddy Jackson has joined up with the Irish squad for the matches against Japan on 17 and 24 June.

Carbery had a mixed game against the US, twice having clearance kicks charged down leading to tries for the Eagles.

The New Zealand-born player had a scan on the injury and did not travel to Japan.

Speaking at Ireland's base in Tokyo on Tuesday, skills coach Richie Murphy confirmed that Carbery was facing at least a month out of action.

"As far as I know it's a either a grade two or a grade three ankle sprain but he's going to be off his feet for a couple of weeks," said Murphy.

"The medical staff say he'll be ready to train in four to five weeks' time."
