Munster have added fullback Felix Jones and Dolphin prop Christy Condon to their Heineken Cup squad.
The two players who were de-registered in their place were John Hayes, who recently retired, and Peter Stringer, who is now on the books at Saracens.
Jones is on the comeback trail following an injury to the stabilising ligaments in his right foot during Ireland’s World Cup warm-up match against France at the Aviva Stadium last August.
The fullback has been back in training since late last year and is in line to make a return to competitive rugby in Munster's RaboDirect PRO12 clash with Aironi at Stadio Zaffanella on Sunday 12 February.
Dolphin's Condon is renowned for his ability in the scrum and he will fill the void filled by 'The Bull' Hayes's retirement. Condon has previously played for Munster A.
