Cardiff Blues' Tomos Williams and Cory Allen have been called up to the Wales squad for the autumn test series.
Scrum-half Williams, who recently signed his first professional contract at BT Sport Cardiff Arms Park, has been called upon as injury cover, following an injury to Rhys Webb during Wales' 8-32 loss to Australia on Saturday.
Meanwhile, centre Allen, who has won four international caps to date, links up with the squad to replace Tyler Morgan. The Newport Gwent Dragons centre has been released from the squad following a hamstring injury.
