His European career kicked-off against Cardiff Blues in 1996 in the Heineken Cup and, in all, he made 65 European appearances for Wasps - 57 in the Heineken Cup and eight in the Amlin Challenge Cup.
He made his debut in the 1999 World Cup against Tonga at Twickenham and went on to win 78 caps for England and played in three World Cup tournaments. He won an MBE as part of the English squad that won the Webb Ellis Trophy in 2003 and came on as a replacement in the 2007 final in Paris.
He also toured South Africa with the British & Irish Lions in 2009, playing in the third Test victory over the Springboks in Johannesburg. His last Test outing was as a replacement for England in their RBS 6 Nations victory over Wales in Cardiff in February this year.
Worsley joined the Wasps academy in 1993 as a 16-year-old and went on to make more than 300 appearances for the club. As well as picking up three European medals, he also won four Premiership titles and three Powergen Cup winners medals.
"Last season I suffered an injury to my neck that has effectively ended my career. Since March I've been following medical and rehab advice, but it didn't help," explained Worsley.
"Restarting contact work during the England World Cup camp made it obvious that I could not continue. My life as a rugby player started at Welwyn under 9s and finished in an England training session.
"I want to say thanks to everyone who helped me on that path. I'm proud of what I achieved and how I played the game."
