A lock who has played for various club sides, Luke Gross earned 62 caps for the USA between 1996 and 2003. Gross was the all-time caps leader for the USA, until Mike MacDonald broke his record in 2011.
Gross played basketball for the Marshall University Thundering Herd for two seasons (1991–92 and 1992–93). Gross started his rugby career far later than most international players, even those from countries like the USA where rugby is not a major sport, not taking up the sport seriously until age 24, after he had attended Marshall University. He began his rugby career with the Cincinnati Wolfhounds. His 6"9' frame gave him a considerable presence in the line-out.
Although he was named to the USA squad for the 2007 Rugby World Cup, and played in the 2007 squad's final warmup against Celtic League side Munster, he did not play in the World Cup itself. Gross last played rugby for the Doncaster Knights, who play in National Division One, the second level of the game in England.
He now works at the USA Rugby National Office in Boulder, CO as the High Performance Player Development Manager.
