"Myself, the management, the captain, [stand-in director of England cricket] Andy Flower, the board - everyone had a bit of a say and basically thought for his wellbeing it was good to get him back around the cricket". Hes desperate to get out there, put in performances and concentrate on his cricket now.
In a separate interview with BBC radio, Root, a friend of Stokes's since their days together in junior cricket, was asked if he felt his fellow 27-year-old was ready to return to the Test arena.
All-rounder Stokes had been added to England's 13-man squad on Tuesday after being acquitted at Bristol Crown Court in the trial that followed a fight outside a nightclub in the city in September.
Skipper Joe Root Root admitted that dropping Curran was "probably one of the most hard decisions I've had to make as captain" - the Surrey player averaging 37 with the bat and 24 with the ball so far in his three Tests.
India coach Ravi Shastri said the tourists would have no qualms playing against Stokes, who took four for 40 as England completed a hard-fought 31-run win in the first Test at Edgbaston earlier this month. "We assessed his fitness as well, over the course of the two days, and made that call".
"That is all part and parcel of making sure you feel ready to play".
Bayliss, who has been England's head coach since 2015, said the Stokes case - combined with disciplinary issues during England's tour of Australia last winter - had prompted the team to reflect on its behaviour.
England: Cook, Jennings, Root (capt), Pope, Bairstow (wkt), Stokes, Buttler, Woakes, Rashid, Broad, Anderson.
And when asked if the Durham star had apologised again to the squad at Trent Bridge, Root answered: "That is for us and within our dressing room".
Curran, 20, was named man of the match after the first Test at Edgbaston, after he claimed five wickets and scored 87 runs in just his second Test.
"Sam misses out, Ben comes into the side", Root said at a media conference on Friday. For us the priority is just to win games of cricket. "There are still a lot of things that need to happen and we can't really look too far ahead until (they) have taken place", Root said.
