Elsewhere, while local clubs across Wales prepare for the start of the season, Crynant RFC are hosting a family fun day on Saturday with the prospect of a Guinness World Record being broken in the process.
As part of the WRU's Join the Beat campaign, the club is calling on as many members of the local community as possible to get involved in beating the current world record of 279 consecutive passes of a rugby ball.
Taking place at Woodland Parks playing fields from midday, the world record attempt will be followed by a family fun day.
The event is being held with the aim of engaging members of the local community in their local rugby club so if you are in the area head down to be a part of a world record attempt.
In a fitting end to a weekend feast of rugby, the inaugural Colin Hillman Sevens takes place on Sunday at the South Wales Police Rugby Ground in Waterton Cross, Bridgend with 10 teams competing.
Former Wales Sevens coach Hillman died in 2009 with the tournament, a brainchild of Colin's friends and colleagues, taking place in his memory.
The rugby competition takes place alongside a hog roast and BBQ with an outside licensed bar. There will also be children's rides, stalls and a raffle on the day.
As well as playing for a number of Welsh clubs, Hillman also played for the Barbarians and Wales Sevens as his name became heavily associated with sevens both in a playing, coaching and managing role.
With many other rugby tournaments and events also taking place this weekend, make the most of the Bank Holiday weekend by heading down to see a game, attend an event or support your local club in whatever way possible.
