48th Annual New York 7s - Nov 25, 2006    
The NEW YORK 7s TOURNAMENT is the largest sevens tournament in the United States. The tournament has been held on the Saturday following Thanksgiving since 1959 and traditionally marks the end of the Fall rugby season in the New York Metropolitan area.

With teams and players traveling from as far away as Central and South America, South Africa, Australia, the UK, France, Canada, and many other countries, the level of play is truly spectacular. Each year the New York Rugby Club plays host to nearly 100 rugby clubs that come to New York for world class competitive rugby and great fun in one of the world’s greatest cities.
