Jos Buttler is to replace Ben Duckett in England's team for the third Test with India, while Stuart Broad and Zafar Ansari will miss Mohali through injury.
Left-hander Duckett has averaged just six across the five-match series' first two games, having lost his spot at the top of the order to the impressive Haseeb Hameed.
Duckett fell in each of his innings to India's star off-spinner Ravichandran Ashwin.
Buttler's call-up will also prompt a reshaping of the England order. Moeen Ali is set to bat at four, followed by Jonny Bairstow with Buttler - playing as a specialist batsman - at seven.
"I can tell you that Jos is coming in to play and Ben misses out," England captain Alastair Cook told a news conference.
Buttler has a Test average of 30, but has played only a solitary County Championship game since being dropped from the Test team on last year's tour of the UAE to play Pakistan.
"We're dealing with a very talented guy and he's earned an opportunity to come and play here," Cook added.
"Playing as a specialist batter at seven is quite unusual but Jonny has been in outstanding form and it gives him a chance to bat a bit more and takes the pressure off Jos.
"What we do know is that Jos is an incredibly good cricketer.
"It's not ideal circumstances, not having had any practice out here with the red ball or having played a huge amount, but sometimes when the pressure is off you can come out and play and do something special."
Duckett, 22, has over 3000 runs to his name in 2016 for Northamptonshire and England and Cook is sure he will come back on the international scene.
"He won't be the only good player that's been dropped," Cook added. "He has an England future, there is no doubt about it.
"He is a very talented guy with a lot ahead of him and it's amazing chatting to him saying 'I thought I was a pretty good player of spin' and he is a good player of spin, he's just got an issue which has been found out quite quickly, as can happen in these parts of the world and international cricket.
"So he can go away and address that and come again. It's just a blip in his career."
Chris Woakes will replace Broad, stricken by a tendon injury in his foot, but Cook stopped short of naming a full side as he ponders Ansari's replacement.
Veteran spinner Gareth Batty would keep England's attack configured with three spinner and three quick bowlers, although Steven Finn could be drafted in at a venue that has historical benefits for seam bowling.
