When young prop Harri O'Connor was called into the Wales squad for the upcoming tour of South Africa, it's likely more than a few eyebrows were raised.
The uncapped Scarlets tight-head might have a bright future in the game, but the 21-year-old is certainly on the greener side of things. He's played just 207 minutes of senior rugby and started just one competitive match.
Granted, players have come in to the international fold with less experience - Christ Tshiunza had just 64 minutes under his belt before being capped last autumn - but prop is a bit of a different proposition. Particularly in South Africa.
