Well could anyone of you who knows cricket rules well can let me know if having a squash ball inside the glove is legal. If not, the i believe its equivalent to taking drugs. Gilchrist had an unfair advantage which is not in line with the cricketing rules.
There is nothing wrong in having something with in Gloves. As long as he is not getting that in contact to the ball.
Had he had anything on his bat that would have helped him... then it would have been illegal. For something within gloves, which is used only for one's comfort, there is nothing wrong in it
