Warren Gatland has made the call to bring in reinforcements in order to protect his British & Irish Lions Test squad.
The first Test against New Zealand is just a week away and with a midweek match against the Chiefs on Tuesday, plus one against the Hurricanes on June 27, he has made it clear that he needs extra numbers.
The news that a quartet of Welshmen and two Scotland internationals will join the touring party has caused some debate. But while that continues we take a closer look at Gatland's new Lions.
Hooker Dacey earned his fourth Wales cap against Tonga at Eden Park on Friday as he made his first international start.
His experience at regional level is greater having made his competitive debut for the Cardiff Blues back in September 2010.
The front-row forward has notched up 68 starts and 50 appearances off the bench for the region.
In the 2013/14 season the 27-year-old was their top try scorer and this season finished with a tally of six tries in the Guinness PRO12 and Challenge Cup.
Francis joined the Exeter Chiefs from London Scottish back in 2014.
The prop has since played in 43 matches for the current Aviva Premiership Champions and came off the bench during their final win at Twickenham last month.
Back in April he was linked with a move to the Cardiff Blues on a dual contract with the Welsh Rugby Union but that did not come to fruition.
At international level he has 23 caps and the tight-head prop started against Tonga in Eden Park.
Newport Gwent Dragons' lock Hill earned his first international cap for Wales last year in the autumn series against Australia and has made two starts for his country.
His four other appearances for Wales have arrived off the bench and this summer he was named vice-captain for their matches against Samoa and Tonga.
At club level he's made 77 outings for the Dragons having moved there in November 2013 following spells with Moesley RFC and the Cardiff Blues.
Scarlets' scrum-half is a more familiar face that will join up with the British & Irish Lions.
He joined their academy back in 2006 and has been a regular fixture for the region having made 150 appearances.
Davies was an integral part of Wales' 2015 Rugby World Cup campaign and scored that memorable try against England at Twickenham.
He has 25 Wales caps to his name and like Hill, Francis and Dacey started against Tonga at Eden Park.
Allan Dell made his Scotland debut against Australia in November 2016.
The loose-head prop moved to Scotland from South Africa to sign for Edinburgh in 2014.
Dell attended Queens College in Eastern Cape and eligible to play for Scotland through his grandmother who was born in Paisley.
The 24-year-old has 29 international caps for Scotland -- all starting appearances -- and comes into the Lions camp off the back of their historic win over Australia in Sydney.
The fly-half learned his trade at Falkirk and arrived at the Glasgow Warriors in the summer of 2012 after impressing at club and U20s level.
He has 490 points to his name for the Warriors and another 77 in the blue of Scotland.
