Cardiff hooker Liam Belcher has been ruled out of Wales' summer matches because of a neck injury.
Belcher, 30, was one of four hookers in the original squad named by head coach Steve Tandy alongside Cardiff club-mate Evan Lloyd, Scarlets front rower Ryan Elias and captain Dewi Lake.
Wales say Belcher suffered the injury during Cardiff's United Rugby Championship (URC) quarter-final play-off defeat against Stormers at the end of May and he has failed to recover in time.
No replacement has been announced with Dragons duo Brodie Coghlan and Elliott Dee, who will line up for the Barbarians against Wales this weekend, as potential options.
Cardiff captain Belcher is the third player to pull out of the summer series following injuries to Bath back Louie Hennessey and tight-head prop Keiron ******* iratti.
