Ospreys back-rower, James King, will miss the Wales summer tour after sustaining an ankle ligament in the PRO12 semi-final against Munster last weekend.
He has had the injury scanned and met with specialists, the outcome being that he will be unavailable for selection for up to four months.
Aaron Shingler from the Scarlets has been called up in his place. Meanwhile, uncapped Exeter Chiefs fullback, Phil Dollman, replaces Cardiff Blues youngster, Rhun Williams.
Wales face Tonga (16th June) and Samoa (23rd June) on tour.
