The 27-year-old is now plying his trade for the Rajasthan Royals in the Indian Premier League, where he has been in fine nick, scoring five consecutive 50s.
Although regarded as a wicketkeeper-batsman, The Telegraph believe Buttler will bat at seven but Jonny Bairstow will keep the gloves in his possession.
"The first thing we talked about as a selection panel - and it coincided with one of my first trains of thought coming into the job - was how could we..."
Buttler is again in scintillating form in limited overs cricket, however, having recorded five consecutive 50s for the Rajahstan Royals in the IPL.
Vince, who was recalled to the Test squad for the Ashes, in spite of a mediocre start to his career against Sri Lanka and Pakistan in 2016, made an attractive 83 in his first Test innings of the winter, at Brisbane in November, and signed off with 76 against New Zealand at Christchurch last month.
He has featured in just 16 first-class matches but new selector Ed Smith is confident Bess has shown enough to suggest he can make the step up.
Somerset's Dom Bess was shopping in IKEA store when England Chief Selector Ed Smith called him up to confirm his selection in England's first Test squad against Pakistan. Other English players who will accompany Buttler on the flight back to England are Ben Stokes, Chris Woakes and Mark Wood (already back).
The 27-year-old Buttler last played a Test against India on their tour to the subcontinent in 2016.
Opener Mark Stoneman hangs on to his position and there is also a potential debut for Somerset off-spinner Dom Bess. The selection panel feels that this is the flawless moment to reintroduce Jos to Test cricket, where he has already enjoyed some success, including a stint playing as a specialist batsman at number seven. "He has impressed everyone with his performances for Somerset and when he has been given opportunities with England representative teams", said Smith. "With Jack Leach missing out, the selection panel wanted to invest opportunity in a young spin bowler".
Contrast that confident mindset to their recent Test match performances, where Trevor Bayliss' teams have played timidly and lost five of their last seven tests.
Buttler, Stokes and seamer Chris Woakes have not played county cricket this season because of IPL commitments, while pace bowler Mark Wood took 6-46 in his only game for Durham after returning home early from the IPL.
