Liam Davies began his professional rugby career with the Llanelli Scarlets and signs with the Blues until the end of the season
Davies made his Scarlets debut while still in the region's development squad, playing against Cardiff Blues in September 2005 and went on to make 43 appearances for the West Wales region.
In June 2008, Davies signed for Brive on a two-year contract before moving back to the UK, having spells with the Ospreys, London Welsh, Scarlets and the Dragons.
Speaking of the signing, Cardiff Blues Director of Rugby, Phil Davies said,
“Liam is a player that I am familiar with having coached him as a 19 year old in the Scarlets.
“He is a very talented scrum half who has a great pass, a good kick and does the basics well.
“He played alongside Andy Goode in Brive and has come home looking for an opportunity to play.
“He will give us extra cover at scrum half for the rest of the season with Rob Lewis having returned to London Welsh on a loan spell.”
