Cardiff Blues have strengthened their front row with the signings of hookers Ryan Tyrrell and Marc Breeze as well as prop Jamie Corsi.
Tyrrell and Breeze will help cover for the loss of hookers Gareth Williams, who is being forced to retire due to a neck injury, and T Rhys Thomas, who is undergoing knee surgery.
Australian Tyrrell, 27, played Super Rugby with Western Force in 2010 before suffering a neck injury which required surgery, while the 24-year-old Breeze joins from Aberavon RFC having previously played for Ospreys and London Welsh.
Tight-head prop Corsi, 23, has represented Wales at under-16, 18, 19 and 20 age groups and was selected for the Wales senior squad to tour Australia in May 2007. At the end of the 2008-09 season Corsi left Newport Gwent Dragons and signed for Scarlets before joining Wasps. He has also played club rugby in New Zealand.
Tyrrell said: "It's been good, so I couldn't have asked for a better settling in period, from the players and coaching staff.
"I've been very impressed with the facilities and that was a massive decision in me hoping to sign. Just seeing the facilities and how the players react to it makes you want to be part of it.
"The set-up here is as good as, if not better than the one we had at Western Force."
