26th May: Chennai S. Kings v Mumbai I, 14:30 GMT
24th-28th May: 2nd Test, Headingley
Both players were reported during the match between the two sides, which was won by England by the margin of 100 runs at the Manuka Oval in Canberra.
Fast bowler Gunn's short balls and off-spinner Fernando's quicker deliveries raised concerns with the umpires.
Last month, Gunn was suspended from playing state cricket in Australia following similar concerns although she is due to appeal.
Both players will now have to undergo immediate assessment of their action with remedial action if required.
