Speaking of his decision Rees said,
"I've had a fantastic time at the Blues since joining in 2007 and there have been many highlights. In particular winning both the EDF Energy & Amlin Challenge cups, and the unforgettable Heineken Cup semi-final penalty shootout versus Leicester"
"Cardiff Blues are currently in a transition period and I believe now is the right time to throw myself into a new challenge. There's a great group of boys at the Blues and I really enjoy training with them every day. I'd like to thank all of the supporters who have been great with me since joining, and Dai Young for his contribution to my career. I look forward to ending the season well with the Blues in both the Rabo & Heineken Cup!"
"I'm currently considering various options for next season and will confirm my destination in the forthcoming weeks."
