Jack Crowley started his first Test match for Ireland against Australia on Saturday night - but only found out he would be playing 20 minutes before kick-off.
The Munster man replaced captain Johnny Sexton, who was a late withdrawal after picking up an injury during the warm-up.
Crowley, 22, only made his international debut seven days previously when coming on for Joey Carbery five minutes into the second half against Fiji, with Ireland going on to win that game 35-17.
