Harlequins new signing Paul Volley has been named as the club's captain.
Volley won the Premiership and Heineken Cup with Wasps
The 34-year-old former Wasps flanker, who joined from French side Castres over the summer, takes over the role from Andre Vos.
"I am over the moon, it will be a huge honour to lead such a world-famous club," he said.
"My short-term objectives are to earn the respect of my team-mates and over the next two years I am confident we can achieve our goals."
Volley won the Premiership and the Heineken Cup during his 16 years at Wasps before leaving for France in 2004.
He has also represented England A and England under-21s.
"Some may find it strange to select a player who has only recently joined the squad to take over as captain," said Quins rugby director Dean Richards.
"However, Paul has captained sides before in his career and has tremendous experience, particularly of the club game in England.
"I have no doubt that he'll lead by example both on and off the pitch, and be an inspiration to others within the team.
"I would like to thank Andre for the way he has captained the side, he has been a tremendous servant to the club and we're delighted that he's decided to stay on for another season. However, he felt the time was right for a change of leadership."
Volley was one of six signings announced by Quins in April as they build their squad in preparation for a return to the Premiership.
Harlequins' Argentine lock Pablo Bouza has left the club to join relegated Leeds.
Bouza, 33 and capped 33 times, replaces Chris Murphy, who has retired from professional rugby to start a new career as a land surveyor.
