The Blues have signed Gavin Evans from the Scarlets to fill the void left by the departing Jamie Robinson.
The hard tackling centre has been capped once by Wales (as a sub against Pacific Islands in 2006) and has played 75 games for the Scarlets since making his debut on tour to Slovenia in 2003.
The 24-year-old has scored 11 tries for the Scarlets and came through the academy system at Stradey Park.
Speaking of the signing, Cardiff Blues Director of Rugby David Young said, "Once Gavin had made the decision to leave the Scarlets to experience a different environment, we were obviously very pleased to hear he was interested in joining the Blues."
"Although he is a young player he has gained a lot of experience during his career at the Scarlets."
"He is a player of high quality and hopefully we can help him fulfill his undoubted rugby potential at the Blues - he will be another great addition to our squad."
