Pranab Roy and Kiran More, both former Test players, lodged complaints with the board that Maharashtra batsman Abhijit Kale offered them money to secure selection to India's senior team.
Kale, 30, who denied any wrongdoing, has been suspended from all cricket until an investigation, to be conducted by the country's bar council chairman D.V. Subba Rao, is completed.
But Kale has won support from players who have protested against his suspension.
"The Indian Cricket Players' Association (ICPA) feels that the player deserves a fair hearing," Arun Lal, former Test opener and secretary of the ICPA, said in a statement.
"There should be no question of suspension before the inquiry is completed."
The Indian media has, meanwhile, reported allegations from across the country by other domestic players, who allege local selectors have often demanded bribes from them.
Kale has scored 6,806 runs in 84 first-class games at an average of 58.67, including 24 hundreds.
His only appearance for India was against Bangladesh in a one-day tri-series match in Dhaka in April.
