Split the webbing

Zaheer to Dravid, no run, back of a length outside off, Dravid flashed hard at that, a thick outside edge, Sachin at a widish slip, he dived forward, kept his eyes on it, took it cleanly, the ball looked like it settled in Sach's hand, he is claiming it, but Dravid does not think so, he waits for the third ump, Sachin has split the webbing on his hand, the hand is bleeding, Daryl Harper feels that the ball has touched the ground, Dravid survives

Please explain to me the emboldened parts.
