Lynagh Junior played for England up to Under-19s level and his father is an Australia legend.
But the 23-year-old bagged a try for Italy in Saturday’s momentous clash with Scotland.
The wing was even called up once by former Red Rose boss Eddie Jones for an England training session.
But he has never been part of Steve Borthwick’s plans since Jones was replaced as head coach in December 2022.
Lynagh was born in Treviso, Italy, but grew up in England.
And he’s been with Premiership club Harlequins since 2019.
His Azzurri call-up comes after he announced he will join Italian giants Benetton next season.
But although he started his international carer with a fine score, matching the achievements of Lynagh Senior will be almost impossible.
The 60-year-old was vice-captain when the Wallabies won the 1991 World Cup.
And when he retired after defeat against England in the WC quarter-finals four years later, he’d won 72 caps.
He was also the-then world record points-scorer with 911 points.
Meanwhile, son Louis had a dramatic introduction to Six Nations rugby in more ways than one.
He notched Italy’s second try amid a thrilling second half.
He sped onto a grubber kick, fended off a couple of potential tackles and went over.
And as Italy scented a famous win, he was replaced by Federico Mori on 71 minutes following an exciting baptism.
