Wales have announced that Scarlets backs coach Stephen Jones will not form part of the nation's coaching staff for the June Tests against Tonga and Samoa.
With Scarlets having finished third in Pro12, they face a semi-final clash with Leinster on May 19 and Jones felt unable to adequately fulfil his international commitments based on that workload.
The former Wales fly-half told the Wales Rugby Union website: "Firstly, I would like to thank [interim head coach] Robin [McBryde] for his support and understanding on this matter.
"It was a huge honour to be named as part of Robin's coaching set-up for the summer tour and I am grateful to Robin for giving me that opportunity.
"Having said that we are delighted, as a region, to be in a position to be playing for silverware and the Scarlets has to take precedence. Reaching the play-offs means an extended season and increased workload meaning that I can't give my undivided attention to preparing for the tour.
"I wish the coaching group, and the players alike, the very best of luck in the two-Test tour, but am also looking forward to the next few weeks with the Scarlets as we push for a place in the final."
Last week Cardiff Blues coach Danny Wilson also withdrew from Wales' team, which will be led by McBryde with Warren Gatland on British and Irish Lions duty.
Wales have named a 32-man squad featuring 13 new faces.
