Proceedings start in Jedburgh with the ribboned ball being thrown into a ruck of the two teams.
One team, the Uppies, try to take the ball towards the town’s castle while the Doonies attempt to carry it towards the Jedwater.
Charlie Young, president of the Jethart Callants Club, explained to the King the history of the lawless sport during the match.
He said: “King Charles got a bit of a shock when the play swung in his direction and a few of the security guys had to come a bit closer.
“But what an honour for us to have the King put the ball up and into play.”
