Rugby fans gear up for summer Sevens heaven
A total of 12 clubs from five continents will descend on the city in August to battle it out at Thomond Park.
Instead of the usual 15-a-side match, the clubs will field teams of seven, making for a lot more open games, Mr Howlett said.
"It's a fast, exciting game with a lot of tries, a lot of running with the ball.
"It's something a lot of us grew up playing. It will be an exciting tournament for the Limerick crowd," he added.
The inaugural Limerick World Club Sevens Festival is pencilled in for August 9 and 10 and the teams confirmed include Saracens, New South Wales Waratahs, Stade Francais, Moscow, Auckland, New York, Vancouver, South Africa's Blue Bulls and Western Province, and Munster Rugby.
It will be held the weekend before this year's World Club Sevens event in Twickenham with many of the same teams taking part in both.
"We have been looking for this type of event in Limerick for some time," said Limerick Marketing Company chief executive Eoghan Prendergast.
The sport is to be included as an Olympic event at the 2016 Games in Rio.
Tickets went on sale yesterday and are available on www.ticketmaster.ie and from all usual outlets, including Thomond Park stadium.
