Zai Bennett, Controller, BBC Three said: "This exciting basketball fixture between the Great Britain and the USA is the perfect way for BBC Three to get ready for our comprehensive coverage of London 2012".
"To have the BBC support the GB versus USA men's and women's basketball games in Manchester is hugely significant for the on-going growth of the sport in the UK," said Dan Markham, Vice President NBA EMEA. "The cross-platform visibility the BBC coverage will provide is fitting for a sport that is enjoyed by millions of fans around the globe."
