Johnny Sexton missed Ireland's win over Australia after hurting his calf in the warm-up, Andy Farrell has revealed.
The Ireland captain was withdrawn from the starting XV just 20 minutes before kick-off at the Aviva Stadium, with Munster fly-half Jack Crowley, who only made his Test debut last weekend, replacing him.
Farrell said after the game: “Johnny went out to do some kicking before the warm-up and he hurt his calf."
