BT Sport viewers can look forward to live coverage of the 2014 Premiership Rugby 7s Series during July and August.
The annual festival of small-sided rugby union - now in its fifth year - has been expanded in 2014 to include the four Welsh regions.
This means that as well as the 12 top-flight domestic teams, the Cardiff Blues, Newport Gwent Dragons, Ospreys and Scarlets will take part.
With 16 teams entering the 2014 Premiership Rugby 7s, there are now four qualification groups instead of three, and eight teams will participate in finals day.
The Welsh regions get the action underway at the BT Sport Cardiff Arms Park on Saturday July 26th, when the two teams to progress from Group A will be decided.
Group B will be contended on Thursday July 31st, with the three West Country sides - Bath Rugby, Exeter Chiefs and Gloucester Rugby - and London Irish competing at Kingsholm Stadium.
The following day (Friday August 1st) will see Harlequins, London Wasps, Northampton Saints and Saracens fight it out at Franklin's Gardens, in what looks like the 'group of death'.
And Group D will be decided on Saturday August 2nd, with Leicester Tigers, Newcastle Falcons, Sale Sharks and Worcester Warriors lining up at Kingston Park.
The Series Final day will take place on Friday August 8th at Twickenham Stoop, with BT Sport viewers able to enjoy every minute of the action.
Mark Davies, Acting Chief Executive of Regional Rugby Wales, welcomed the news that the four Welsh regions will take part in the tournament.
"There is a lot of pride at stake as well as the opportunity of a place in the Series Final and the chance to be part of what will be a very big family occasion at the World Club 7s at Twickenham in August," he stated.
"We know for sure that Anglo Welsh rugby contests ignite plenty of excitement and passion amongst our supporters and we hope our involvement will add a real edge to the event."
