It is expected Bairstow will continue to keep and Buttler will be deployed as a batsman in the match at Lord's starting next Thursday.
Vince, a shock recall for England's eventual 4-0 Ashes series loss in Australia, made 83 in the first innings at Brisbane in November and ended his southern hemisphere tour with 76 against New Zealand in Christchurch last month.
Buttler, on the other hand, last played in the whites back in 2016 and was overlooked for the Ashes squad.
That meant the stints of Buttler and Stokes, both of whom represent Rajasthan Royals, in the ongoing IPL are over.
The loss against Kolkata Knight Riders couldn't have come at a more bad time for Rajasthan Royals, who are set to lose out two of their biggest global stars in the form of Jos Buttler and Ben Stokes because of worldwide commitments.
Suspect shot at IL high school shooting
His injuries are not considered to be life-threatening. "No students or staff were injured in the incident", officials said. While all Dixon public school were put on lockdown earlier in the day, only Dixon High School remains on lockdown.
The England squad also features Somerset off-spinner Dom Bess, who was given a first call-up.
The 27-year-old is now playing some of his best cricket in the Indian Premier League.
Twenty-year-old Bess has played 16 first-class matches and was impressive in the Champion County match for the MCC against Essex in March, where he took eight wickets in the match and scored a valuable century. "Jos is playing with great confidence and flair, and he will bring unique qualities to the Test team", Smith said about Buttler. In all likelihood, as the sole spinner in the 12 man party, Bess will make his Test debut at the Home of Cricket next week.
Smith said that the youngster had made an excellent start to his first-class career and added: "He has impressed everyone with his performances for Somerset and when he has been given opportunities with England representative teams".
Buttler's return, to bat at number seven, will excite many in a line-up which will see captain Joe Root voluntarily move back up to three, wicketkeeper Jonny Bairstow delighted at a promotion to five and Mark Stoneman hang on to his opener's slot.
