England sacrificed opener Jason Roy to accommodate Brook, who has been marked out as a future superstar of the game because of his explosive batting.
"We'll make the right call here - if he's not fit to play, he's not fit to play," Buttler said.
Brook, an automatic pick in England's test side and part of their T20 World Cup winning team last year, is likely to be the beneficiary of circumstances.
The start of his international career has been outstanding in T20 cricket and in the test format," Buttler said.
We know from test cricket, he can play big innings.
