The United States Eagles have taken the radical step of axing skipper Todd Clever ahead of the Rugby World Cup.

High-profile United States rugby captain Todd Clever has been booted out of the squad ahead of the World Cup for disciplinary reasons.

USA Rugby confirmed in a statement on Tuesday (NZT Wednesday), the 32-year-old had been axed due to "multiple squad conduct violations".

"Such behaviour is contrary to the team culture that players and management have been fostering within the Eagles over time," coach Mike Tolkin said.

"Clearly, this is not a pleasant or desirable circumstance for either party."

Clever was replaced as skipper by Chris Wyles for last weekend's 21-16 loss to Samoa in San Jose, California.

Clever, who spent time playing for North Harbour in New Zealand and Super Rugby with the Lions, had become the face of American rugby with his long hair and respected play at flanker.

He skippered the Eagles against the All Blacks in Chicago last year and has a current contract in Japan.

Clever has played 63 times for the Eagles and was a member of their 2003, '07 and '11 World Cup squads.

The United States have a tough World Cup pool with South Africa, Scotland, Samoa and Japan for the tournament in England that starts in September.
