He progressed well through the system and made his Blues debut on the 27th of January 2006 against Edinburgh.
The Blues go into the match with confidence, with their only defeat in the opening four rounds of this season's RaboDirect PRO12 a19-21 loss at home to Edinburgh in round two.
Having been victorious in their last two home fixtures with Irish provinces they now face an Ulster side that return to action following the tragic circumstances of last week's postponement of the clash with Zebre in Italy.
The Ulstermen have won all three PRO12 encounters so far this season, whilst their only defeat in their last five clashes with Welsh regions came in this equivalent fixture last season.
Speaking ahead of the match Phil Davies said,
"Friday I think will be our sternest test against the Heineken Cup finalists.
"It's going to be Ulster's first game back since the tragic news they received a fortnight ago about Nevin Spence.
"We are paying due respect to the situation Ulster are in and how they feel by matching that emotion and that level of performance.
"Hopefully we will have a great game as a tribute to a great rugby player and a great Ulsterman."
Commenting on Bradley Davies becoming a Blues centurion, Davies added,
"Bradley was one of the first players to have come through the system at the Blues, playing age grade rugby for Blues North and Under 18's before joining the Blues academy.
"He has gone on to perform consistently for the Blues as well as for Wales and I'm sure it's a big day for him.
"Bradley is one of the stalwarts of the Cardiff Blues and I'd like to congratulate him on reaching a landmark 100 games for the region."
