The skipper has left the squad to be with wife Louise for the birth of their third child.
Buttler produced an inspired performance in the second T20 at Edgebaston on Saturday, with his contribution of 84 from 54 deliveries helping the hosts to a 23-run victory.
The 33-year-old's knock, which included eight fours and three sixes, marked the second-highest score by an England captain in a T20I, behind Eoin Morgan's 91 against New Zealand in 2019.
However, the hosts will have to make do without their white-ball skipper in Cardiff, while he could potentially miss the fourth T20 at The Oval on Thursday and some matches at the T20 World Cup, which begins on Sunday.
Moeen Ali will captain England in Buttler's absence, with either Phil Salt or Jonny Bairstow set to deputise as wicketkeeper.
England will begin the defence of their T20 World Cup title against Scotland in the Caribbean on June 4.
