Ospreys prop Aaron Jarvis is heading to New Zealand to provide cover for the injured Paul James and is set to arrive in Auckland on Wednesday.
James is still struggling with a calf injury and looks set to miss both this weekend's first Test in Auckland against the All Blacks and Tuesday's clash with former Super Rugby champions the Chiefs in Hamilton.
Jarvis, who is heading to Clermont next season, trained with the Wales squad for the two weeks before they travelled to New Zealand and was with the squad at Twickenham when they played England.
Capped 17 times by Wales, the 30-year-old was a replacement in the final Six Nations game against Italy in March.
Wales assistant coach Shaun Edwards has confirmed that James will sit out for Wales first two matches.
"You always want a fully fit squad and Paul has been grafting hard to be fully fit particularly for the game on Tuesday," Edwards told the official WRU website.
"Unfortunately it doesn't look as though that is going to happen and we have brought Aaron out as cover."
