The Indian team's media manager Dr R N Baba informed that Fletcher will rejoin the Indian squad in Birmingham, just ahead of their last ICC Champions Trophy group B league match against Pakistan on June 15.
India are already in the semi-finals while Pakistan are out of the tournament after two defeats.
Fletcher joined as Indian coach on a two-year contract after Gary Kirsten guided India to the 2011 World Cup. The BCCI in April this year has extended Fletcher's contract by a year.
