Ireland skipper Johnny Sexton sidelined for four to six weeks

Ireland skipper Johnny Sexton will miss his side's final autumn international game against Argentina to be played on Sunday following an injury.

The 36-year-old twisted his ankle and knee during Ireland's recently concluded win over New Zealand where he was replaced in the 63rd minute and is expected to be sidelined between four to six weeks.

"Captain Johnny Sexton twisted a knee and ankle against New Zealand at the weekend which will rule him out of action for between four to six weeks," read a statement from the Irish Rugby Football Union.

Following Sexton's injury, replacement Joey Carbery kicked three decisive penalties in the final 15 minutes as Ireland registered a 29-20 win over the All Blacks - their third victory over New Zealand in last five games.

Sexton will remain with the squad as they prepare to face the Pumas at Aviva Stadium with Connacht's Jack Carty has been added to the squad.

Carty has played 10 Tests for Ireland - all of it coming during 2019 and was part of the squad that competed in the World Cup that year in Japan.

Meanwhile, Munster forward Gavin Coombes returns to the squad following illness.
