A lot of people here including me, Cricinfo comments and the commentators saw barely anything. Not saying that spot wasn't there it may have been, but there is no way with so much doubt you can call that *conclusive proof*. The DRS is supposed to remove howlers and there is no way that was even close, on-field umpires call should have stood.
Nothing on Snicko or hotspot but the review was overturned :crazy:
Yes there were larger patches of glare moving around but there was a patch of black on the glove and right on that patch a white spot shows up only just after the ball passed. He replayed it several times close together and every time it looked like something made by the ball.
