Iroquois national lacrosse team has now abandoned plans of traveling to the World Lacrosse Championships in Britain on Saturday, after British officials forbade the team from entering the United Kingdom with tribal passports.

The team was held at John F. Kennedy International Airport this week, initially forbidden from traveling with their Iroquois national passports. Britain and the United States had honored these documents until new updated border security rules took effect.

The players were then forced to forfeit two scheduled games. The U.S. State Department then cleared the American-born Iroquois players to attend the tournament under a one-time exemption, but Britain refused to give an exemption.

In a Saturday statement, Chief Oren R. Lyons, the team’s honorary chairman, said that the players did not withdraw from the tournament and that the Iroquois would work on upgrading its documents to international security standards.
