They adopted their current name in 2001 after forming a team partnership with the Newcastle Knights of Australia's National Rugby League, who sent them jerseys.
A serious thunderstorm interrupted the game, and the Knights, who were leading perennial champions the Glen Mills Bulls 18-12, were declared winners.
The Knights made several other playoff appearances, and defeated the Jacksonville Axemen to win the 2009 AMNRL Grand Final.
The Knights have provided a total of nine players to the United States national rugby league team to date, as well as one to Japan.
The following year they joined the USA Rugby League, along with other surviving AMNRL clubs.
